scsi: ibmvfc: Add helper for testing capability flags
Testing the NPIV Login response capabilities is a long winded process of
dereferencing the vhost->login_buf->resp.capabilities field, then byte
swapping that value to host endian, and performing the bitwise test.
Currently we only ever check this in ibmvfc_cancel_all(), but follow-up
patches will need to regularly check for targetWWPN and channelization
support.
Add a helper to simplify checking various VIOS capabilities, namely
ibmvfc_check_caps().
