scsi: lpfc: Fix incorrect request len mbox field when setting trunking via sysfs

Browse source

When setting trunk modes through sysfs, the SLI_CONFIG mailbox command's
command payload length is incorrectly hardcoded to 12 bytes.  SLI_CONFIG's
payload length field should be specified large enough to encompass both the
submailbox command header and the submailbox request itself.

Thus, replace the hardcoded 12 bytes with a clearer calculation by way of
sizeof(struct lpfc_mbx_set_trunk_mode) - sizeof(struct lpfc_sli4_cfg_mhdr).
