Subject[v3][PATCH 4/5] Remove get_init_pts_sb()

From: Sukadev Bhattiprolu <sukadev@linux.vnet.ibm.com>
Subject: [v3][PATCH 4/5] Remove get_init_pts_sb()

With mknod_ptmx() moved to devpts_get_sb(), init_pts_mount() becomes
a wrapper around get_init_pts_sb(). Remove get_init_pts_sb() and
fold code into init_pts_mount().
