MdeModulePkg: ScsiBusDxe: Refactor DiscoverScsiDevice()
Currently DiscoverScsiDevice() returns a boolean which cannot
distinguish a "not found" situation from a real problem like
memory allocation failures.
This patch changes the return value to an EFI_STATUS so that when
memory allocation fails, it will return EFI_OUT_OF_RESOURCES.
Without this change, any FALSE returned by DiscoverScsiDevice()
will result in EFI_OUT_OF_RESOURCES being returned by
ScsiScanCreateDevice(), which will cause a while loop in
SCSIBusDriverBindingStart() to abort before other possible Puns in
the SCSI channel are scanned, which means good devices may not have
a chance to be discovered. If this good device is the boot device,
boot will fail.
