Third set of IIO fixes for the 3.12 cycle.

Two little ones this time:

1) A missing clk_unprepare in adf4350.
2) A missing free of the active_scan_mask when iio_disable_all_buffers is
called during an unexpected device removal.  This leak was introduced by
the fix
3e73cedea3b12672a25a23c5d5ef747604b422df iio: Stop sampling when the device is removed
and hence is a regression fix.
