[PATCH v4 8/9] MdeModulePkg/BdsDxe: Revert "fall back to UI loop before hanging"

[Ruiyu Ni]

Commit d1de487dd2e77f4741abcbd71d19a8c93971fda0
"MdeModulePkg/BdsDxe: fall back to a Boot Manager Menu loop before
 hanging"
changed BDS core to fall back to UI loop when no bootable option
can be launched.
Now since PlatformBootManagerUnableToBoot() is added, the commit
can be reverted.

I will take leave for 1.5 weeks and will not be back until next.next Monday.
Because there are still some internal platform codes that need 
PlatformBootManagerLib modifications which I will make after I am back, 
the open source check-ins will be deferred after the internal 
modification is done.
