ceph: make ceph_msdc_build_path use ref-walk
Encryption potentially requires allocation, at which point we'll need to
be in a non-atomic context. Convert ceph_msdc_build_path to take dentry
spinlocks and references instead of using rcu_read_lock to walk the
path.
This is slightly less efficient, and we may want to eventually allow
using RCU when the leaf dentry isn't encrypted.
