cifs: Fix printing Status code into dmesg

NT Status code is 32-bit number, so for comparing two NT Status codes is
needed to check all 32 bits, and not just low 24 bits.

Before this change kernel printed message:
"Status code returned 0x8000002d NT_STATUS_NOT_COMMITTED"

It was incorrect as because NT_STATUS_NOT_COMMITTED is defined as
0xC000002d and 0x8000002d has defined name NT_STATUS_STOPPED_ON_SYMLINK.

With this change kernel prints message:
"Status code returned 0x8000002d NT_STATUS_STOPPED_ON_SYMLINK"
