Aneesh Kumar K.V 8009f9fb30 ext4: Fix circular locking dependency with migrate and rm.
In order to prevent a circular locking dependency when an unlink
operation is racing with an ext4 migration, we delay taking i_data_sem
until just before switch the inode format, and use i_mutex to prevent
writes and truncates during the first part of the migration operation.
