media: uvcvideo: Fix memory leak of object map on error exit path

Browse source

Currently when the allocation of map->name fails the error exit path
does not kfree the previously allocated object map. Fix this by
setting ret to -ENOMEM and taking the free_map exit error path to
ensure map is kfree'd.

Addresses-Coverity: ("Resource leak")
