fs, nfs: convert pnfs_layout_segment.pls_refcount from atomic_t to refcount_t

Browse source

refcount_t type and corresponding API should be
used instead of atomic_t when the variable is used as
a reference counter. This allows to avoid accidental
refcounter overflows that might lead to use-after-free
situations.
