scsi: sd_zbc: Improve report zones error printout
In the case of a report zones command failure, instead of simply printing
the host_byte and driver_byte values returned, print a message that is more
human readable and useful, adding sense codes too.
To do so, use the already defined sd_print_sense_hdr() and
sd_print_result() functions by moving the declaration of these functions
into sd.h.
