Mikulas Patocka b7f362d641 dm writecache: fix smatch warning about invalid return from writecache_map 
There's a smatch warning "inconsistent returns '&wc->lock'" in
dm-writecache. The reason for the warning is that writecache_map()
doesn't drop the lock on the impossible path.

Fix this warning by adding wc_unlock() after the BUG statement (so
that it will be compiled-away anyway).

Fixes: df699cc16e ("dm writecache: report invalid return from writecache_map helpers")
