rbd: do some refactoring
A few blocks of code are rearranged a bit here:
- In rbd_header_from_disk():
- Don't bother computing snap_count until we're sure the
on-disk header starts with a good signature.
- Move a few independent lines of code so they are *after* a
check for a failed memory allocation.
- Get rid of unnecessary local variable "ret".
- Make a few other changes in rbd_read_header(), similar to the
above--just moving things around a bit while preserving the
functionality.
- In rbd_rq_fn(), just assign rq in the while loop's controlling
expression rather than duplicating it before and at the end of
the loop body. This allows the use of "continue" rather than
"goto next" in a number of spots.
- Rearrange the logic in snap_by_name(). End result is the same.
