rtlwifi: btcoexist: Fix "always true" warning from commit ed364abffd6e

The 0-DAY kernel build testing backend reports the following warning:
drivers/net/wireless/rtlwifi/btcoexist/halbtcoutsrc.c:516 halbtc_bitmask_write_1byte()
warn: always true condition '(bit_mask != 4294967295) => (0-255 != u32max)'

This problem was introduced in commit ed364abffd6e19bec67b7ccda8237213b8b37640,
and arises because the caller of halbtc_bitmask_write_1byte() is using a
u8 rather than a u32 for the data.
