block: rename blk_io_plug_call() API to defer_call()

Browse source 
Prepare to move the blk_io_plug_call() API out of the block layer so
that other subsystems call use this deferred call mechanism. Rename it
to defer_call() but leave the code in block/plug.c.

The next commit will move the code out of the block layer.
