This reverts commit 6461344c318cd43a5494c0302e142a0cbe386d52.
* MdeModulePkg/UsbMass: Fix hot-plug USB CDROM can't be recognized
UsbBootExecCmd() only calls UsbBootRequestSense() to get sense key
when CMD fails.
When POWER ON (29h) ASC returns from REQUEST SENSE, implementation
should retry the CMD, instead of treating this as a SUCCESS.

This reverts commit a662afb5b023a187ef638d3cb0e0c313ad39a7fc.
* MdeModulePkg/UsbStorage: Fix "map -r" cannot detect media change
The above commit fixed the following issue:
When system boots to Shell without CDROM inside USB CDROM drive,
and then user inserts the CDROM with Eltorito file system,
"map -r" cannot show the new ELtorito file system.
The commit caused EFI_MEDIA_CHANGED status returned from
UsbBootDetectMedia().
But that fix exposes another issue:
When issuing ReadCapacity command to certain USB key
(Kingston DataTraveler G3 8GB) after it's hot-plugged, USB device
returns STALL error and RequestSense command returns media changed
sense data. (Most of the USB keys return SUCCESS for ReadCapacity
command after hot-plug.)

When a USB device reports failure for a CMD and REQUEST SENSE returns
Media Changed key, UsbBootExecCmdWithRetry() stops to retry CMD and
returns EFI_MEDIA_CHANGED to caller.
For this case, the CMD should be retried until success, getting
NoMedia sense key or timeout.
The patch updates UsbBootExecCmdWithRetry() to follow the above
rule so EFI_MEDIA_CHANGED is no longer returned.
UsbBootDetectMedia() is updated accordingly.
Because UsbBootGetParams() is called for new plugged USB storage,
and some USB storage devices may report Media Changed key,
UsbBootGetParams() is updated to treat it as a Success.
This change could fix the issue that some USB storage devices
cannot be detected.
