ASoC: atmel-ssc: remove clk_disable_unprepare call from critical section
clk_prepare/unprepare (and indirectly clk_prepare_enable/disable_unprepare)
may sleep and thus cannot be called in critical section.
This patch fix a bug introduced by commit
6f0d94790e
where clk_disable_unprepare was
called with user_lock hold.
