Hao Wu 2df8798274 MdeModulePkg/UfsBlockIoPei: Correct use of 'DeviceIndex' in BlkIO PPI
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.
