pvmove: split pvmove_update_metadata function

So far pvmove_update_metadata (originaly _update_metadata) was
used for both initial and subsequent metadata updates during polling.
With a new polldaemon (lvmpolld) all operations that require polling
have to be split in two parts: The initiating one and the polling one.
The later step will be used from lvm command spawned by lvmpolld to
monitor and advance the mirror on next segment if required.

1) The initiation part is _update_metadata in pvmove.c which performs
only the first update, setting up the pvmove itself in metadata.

2) pvmove_update_metadata in pvmove_poll.c now handles all other
subsequent metadata updates except the last one.

Due to the split we could remove some code. Also some functions were
moved back to pvmove.c as they were suited for initialisation of pvmove
only.
