[PATCH] scsi: qla2xxx: Fix an endian bug in fcpcmd_is_corrupted()

[Dan Carpenter]

We should first do the le16_to_cpu endian conversion and then apply
the FCP_CMD_LENGTH_MASK mask.

I just happened to spot this when I was reviewing something unrelated.
I don't have the hardware to test it, so please review carefully.
