scsi: zfcp: Correct kdoc parameter description for sending ELS and CT

Since commit 7c7dc196814b ("[SCSI] zfcp: Simplify handling of ct and els
requests") there are no more such structures as zfcp_send_els and
zfcp_send_ct. Instead there is now one common fsf structure to hold zfcp
data for ct and els requests. Fix parameter description for
zfcp_fsf_send_ct() and zfcp_fsf_send_els() accordingly.
