For zoned null_blk devices setup without any limit on the maximum number of open and active zones, there is no need to count the number of zones that are implicitly open, explicitly open and closed. This is indicated by the boolean field need_zone_res_mgmt of sturct nullb_device. Modify the zone management functions null_reset_zone(), null_finish_zone(), null_open_zone() and null_close_zone() to manage the zone condition counters only if the device need_zone_res_mgmt field is true. With this change, the function __null_close_zone() is removed and integrated into the 2 caller sites directly, with the null_close_imp_open_zone() call site greatly simplified as this function closes zones that are known to be in the implicit open condition. null_zone_write() is modified in a similar manner to do zone condition accouting only when the device need_zone_res_mgmt field is true. With these changes, the inline helpers null_lock_zone_res() and null_unlock_zone_res() are removed and replaced with direct calls to spin_lock()/spin_unlock().
