libceph: use pg_num_mask instead of pgp_num_mask for pg.seed calc
commit 9542cf0bf9b1a3adcc2ef271edbcbdba03abf345 upstream. Fix a typo that used the wrong bitmask for the pg.seed calculation. This is normally unnoticed because in most cases pg_num == pgp_num. It is, however, a bug that is easily corrected.
