mfd: Fix mismatch in twl4030 mutex lock-unlock

commit e178ccb33569da17dc897a08a3865441b813bdfb upstream.

A mutex is locked on entry into twl4030_madc_conversion().
Immediate return on some error conditions leaves the
mutex locked.

This patch ensures that mutex is always unlocked before
leaving the function.
