wifi: rtw89: refine C2H reg event polling timeout for LPS

Browse Source 
The each of C2H reg event have different polling timeout. Refine the
LPS C2H reg event polling timeout. Otherwise, during SER, the FW has
already crashed, the leave LPS check will wait until timeout expires,
causing the SER recovery to take too long.
