rtlwifi: rtl8821ae: Fix HW_VAR_NAV_UPPER operation
The cast here is wrong. We want to cast the pointer but we accidentally do a no-op cast of the value. We normally want to set us_nav_upper to WIFI_NAV_UPPER_US (30000) but because of this bug we instead set it to 184 on little endian systems and 0 on big endian ones.
