[SCSI] libsrp: fix bug in ADDITIONAL CDB LENGTH interpretation
Fix a bug in the interpretation of the ADDITIONAL CDB LENGTH (add_cdb_len)
field of SRP_CMD requests. According to the SRP specification, the layout
of this single-byte field is as follows:
* Bits 0 and 1 are reserved.
* Bits 2 to 7 represent the ADDITIONAL CDB LENGTH field, symbolically
represented as n.
* Still according to the SRP specification, the ADDITIONAL CDB section
takes 4*n bytes.
Currently libsrp is only used by the ibmvscsi driver. Since the ibmvscsi
driver doesn't support large CDB's, this bug hasn't caused any problems yet.
[jejb: use & ~3 to mask the bits]
