REF:https://bugzilla.tianocore.org/show_bug.cgi?id=1474
Within UfsBlockIoPei, the current implementation of the Block IO(2)
services:
UfsBlockIoPeimGetMediaInfo
UfsBlockIoPeimReadBlocks
UfsBlockIoPeimGetMediaInfo2
UfsBlockIoPeimReadBlocks2
does not handle the input parameter 'DeviceIndex' properly.
According to both of the PI spec and the function description comments:
> DeviceIndex Specifies the block device to which the function wants
> to talk. ... This index is a number from one to
> NumberBlockDevices.
But current codes incorrectly treat the valid range of 'DeviceIndex' as 0
to (NumberBlockDevices - 1).
This commit is to address this issue.
