ASoC: fsl_xcvr: fix missing lock in fsl_xcvr_mode_put()
fsl_xcvr_activate_ctl() has
lockdep_assert_held(&card->snd_card->controls_rwsem),
but fsl_xcvr_mode_put() calls it without acquiring this lock.
Other callers of fsl_xcvr_activate_ctl() in fsl_xcvr_startup() and
fsl_xcvr_shutdown() properly acquire the lock with down_read()/up_read().
Add the missing down_read()/up_read() calls around fsl_xcvr_activate_ctl()
in fsl_xcvr_mode_put() to fix the lockdep assertion and prevent potential
race conditions when multiple userspace threads access the control.
