scsi: implement REQ_OP_ZONE_RESET_ALL

Browse Source 
This patch implements the zone reset all operation for sd_zbc.c. We add
a new boolean parameter for the sd_zbc_setup_reset_cmd() to indicate
REQ_OP_ZONE_RESET_ALL command setup. Along with that we add support in
the completion path for the zone reset all.
