[SCSI] libfc: add fc_fill_reply_hdr() and fc_fill_hdr()
Add functions to fill in an FC header given a request header.
These reduces code lines in fc_lport and fc_rport and works
without an exchange/sequence assigned.
fc_fill_reply_hdr() fills a header for a final reply frame.
fc_fill_hdr() which is similar but allows specifying the
f_ctl parameter.
Add defines for F_CTL values FC_FCTL_REQ and FC_FCTL_RESP.
These can be used for most request and response sequences.
v2 of patch adds a line to copy the frame encapsulation
info from the received frame.
