staging: rtl8723bs: use read_poll_timeout_atomic in _is_fw_read_cmd_down

Browse source

Replace the existing rtw_read8() and do-while loop mechanism with
read_poll_timeout_atomic() from <linux/iopoll.h>, in _is_fw_read_cmd_down()
which is a standard Linux macro, ensuring polling REG_HMETFR efficiently.
