msm: sdio_cmux: Fix for dead-lock on call to receive_cb of channel

In a rare scenario, a thread calls the function
sdio_cmux_is_channel_reset from sdio_ctl_poll
and it gets suspended while acquiring the mutex
logical_ch[id].lc_lock because this mutex is held
by another thread that is suspended while trying
to acquire the mutex rx_lock which is already
acquired by the first thread. This code changes fixes
this issue.
