[PATCH net-next] net: wwan: Fix bit ops double shift

[PATCH net-next] net: wwan: Fix bit ops double shift

[Loic Poulain]

bit operation helpers such as test_bit, clear_bit, etc take bit
position as parameter and not value. Current usage causes double
shift => BIT(BIT(0)). Fix that in wwan_core and mhi_wwan_ctrl.

Fixes: 9a44c1cc6388 ("net: Add a WWAN subsystem")
