fuse: Simplfiy the posix acl handling logic.

Rename the fuse connection flag posix_acl to cached_posix_acl as that
is what it actually means.  That fuse will cache and operate on the
cached value of the posix acl.

When fc->cached_posix_acl is not set, set ACL_DONT_CACHE on the inode
so that get_acl and friends won't cache the acl values even if they
are called.

Replace forget_all_cached_acls with fuse_forget_cached_acls.  This
wrapper only takes effect when cached_posix_acl is true to prevent
losing the nocache or noxattr status in when posix acls are not
cached.

Always use posix_acl_access_xattr_handler so the fuse code
benefits from the generic posix acl handlers as much as possible.
This will become important as the code works on translation
of uid and gid in the posix acls when fuse is not mounted in
the initial user namespace.
