fix a double lock of a buffer head which deadlocked us on
small blocksize filesystems. Also relocate a balance dirty
call so that we do it a little less often.
In the unwritten extent case, remove a call to lock_buffer()
added in the last mod, this was incorrect and caused
a deadlock. Also instead of doing balance dirty each
time we dirty a buffer head, do it once for the whole
page_state_convert call.

Move all allocation requst flags to a seperate set of defines

conversion go into the allocator the same way all other
requests do. Fix a reference count issue which caused use

Hah - knew if I stared at it long enough I'd see a way to do this.
Removes the page array I created to hold pages until we could setup
enough state for the IO completion handlers to do their thing - we
now make more judicious use of the atomic pb_io_remaining field to
ensure the IO completion handlers are never called before the pb is
completely setup.  Also fixed several comments, and renamed several
functions which are no longer specific to delayed allocation (well,
they weren't really anyway...)
