Max Filippov 6b2849b3e0 xtensa: fix lock_mm_and_find_vma in case VMA not found 
commit 03f889378f upstream.

MMU version of lock_mm_and_find_vma releases the mm lock before
returning when VMA is not found. Do the same in noMMU version.
This fixes hang on an attempt to handle protection fault.

Fixes: d85a143b69 ("xtensa: fix NOMMU build with lock_mm_and_find_vma() conversion")
