shmem: move shmem_mapping out of line
shmem_aops really should not be exported to the world. Move
shmem_mapping and export it as internal for the one semi-legitimate
modular user in udmabuf.
This effectively reverts commit 30e6a51dbb05 ("mm/shmem.c: make
shmem_mapping() inline"). which added a bogus shmem_aops non-GPL export
for no reason whatsoever as there as no shmem_mapping call outside of
core MM code at that point.
