[PATCH 1/7] drbd: rename drbd_worker.c to drbd_sender.c

["Christoph Böhmwalder" <christoph.boehmwalder@linbit.com>]

The "worker" thread has long since become the thread that sends data
and resync requests to the peer; the receiving side lives in
drbd_receiver.c. The out-of-tree DRBD 9 code base has called this file
drbd_sender.c for years.

Rename the file up front, with no content change, so that the upcoming
DRBD 9 rework of this thread shows up as a modification of one file
instead of the removal of one file and the addition of another.
