dma-debug: avoid spinlock recursion when disabling dma-debug
Ville Syrjälä authored 
commit 3017cd63 upstream.

With netconsole (at least) the pr_err("...  disablingn") call can
recurse back into the dma-debug code, where it'll try to grab
free_entries_lock again.  Avoid the problem by doing the printk after
dropping the lock.
