[PATCH] ceph: fix posix acl couldn't be settable

[xiubli@redhat.com]

From: Xiubo Li <xiubli@redhat.com>

For the old mount API, the module parameters parseing function will
be called in ceph_mount() and also just after the default posix acl
flag set, so we can control to enable/disable it via the mount option.

But for the new mount API, it will call the module parameters
parseing function before ceph_get_tree(), so the posix acl will always
be enabled.

Fixes: 82995cc6c5ae ("libceph, rbd, ceph: convert to use the new mount API")
