[PATCH] staging: rtl8723bs: make rtw_register_tx_alive() return bool

[PATCH] staging: rtl8723bs: make rtw_register_tx_alive() return bool

[Hungyu Lin]

rtw_register_tx_alive() only reports whether the transmit path can
continue, and its only caller treats the return value as a boolean.

Change the return type to bool and replace _SUCCESS and _FAIL with true
and false. Update the caller accordingly.

No functional change.
