nvmet: fix a width vs precision bug in nvmet_subsys_attr_serial_show()
This was intended to limit the number of characters printed from
"subsys->serial" to NVMET_SN_MAX_SIZE. But accidentally the width
specifier was used instead of the precision specifier so it only
affects the alignment and not the number of characters printed.
