scsi: megaraid_sas: Replace undefined MFI_BIG_ENDIAN macro with __BIG_ENDIAN_BITFIELD macro

commit b9d5e3e7 upstream.

MFI_BIG_ENDIAN macro used in drivers structure bitfield to check the CPU
big endianness is undefined which would break the code on big endian
machine. __BIG_ENDIAN_BITFIELD kernel macro should be used in places of
MFI_BIG_ENDIAN macro.
