Function ceph_get_inode() never returns NULL; instead it returns an
ERR_PTR() if something fails. Thus, the check for NULL in parse_longname()
is useless and can be dropped. Instead, move there the debug code that
does the error checking so that it's only executed if ceph_get_inode() is
called.

Changes since v2:
As suggested by Xiubo, moved the error checking into the 'if (!dir)'
block.

LGTM.
Applied to the testing branch and will run the tests.
Thanks Luis.
