fs/namespace: use __getname() to allocate mntpath buffer

mnt_warn_timestamp_expiry() allocates memory for a path with
__get_free_page() although there is a dedicated helper for allocation of
file paths: __getname().

Replace __get_free_page() for allocation of a path buffer with __getname().

Christian Brauner <brauner@kernel.org> says:

Pass PATH_MAX (not PAGE_SIZE) to d_path() to match the size that
__getname() actually allocates, and drop the now-unnecessary NULL check
around __putname() since __putname() handles NULL.  Both per Jan Kara's
review feedback, acked by the author.
