shmdt: use i_size_read() instead of ->i_size
Andrew Morton noted
http://lkml.kernel.org/r/20141104142027.a7a0d010772d84560b445f59@linux-foundation.org
that the shmdt uses inode->i_size outside of i_mutex being held.
There is one more case in shm.c in shm_destroy(). This converts
both users over to use i_size_read().
