bpf: fix lockdep false positive in stackmap

[ Upstream commit 3defaf2f15b2bfd86c6664181ac009e91985f8ac ]

Lockdep warns about false positive:

since rw_semaphore is released in a different task vs task that locked the sema.
It is expected behavior.
Fix the warning with up_read_non_owner() and rwsem_release() annotation.
