V4L/DVB: davinci: don't return under lock on error path

Browse Source 
If the kmalloc() failed for "ccdc_cfg = kmalloc(...);" then we would exit
with the lock held.  I moved the mutex_lock() below the allocation
because it isn't protecting anything in that block and allocations are
allocations are sometimes slow.
