scsi: fc: start decoupling fc_block_scsi_eh from scsi_cmnd
Scsi_cmnd is an unsuitable argument for eh_device_reset_handler(), eh_target_reset_handler(), and eh_host_reset_handler() which do not have the scope of one single SCSI command. These callbacks tend to use fc_block_scsi_eh() requiring scsi_cmnd. In order to start decoupling above eh callbacks from scsi_cmnd, introduce a new variant of the function called fc_block_rport() taking an fc_rport as argument. Refactor the old fc_block_scsi_eh() to simply delegate to fc_block_rport().
