[PATCH 2/4] UBIFS: remove dead GC LEB recovery piece of code

[Artem Bityutskiy]

From: Artem Bityutskiy <Artem.Bityutskiy at nokia.com>

This patch removes a piece of code in 'ubifs_rcvry_gc_commit()' which is never
executed. We call 'ubifs_find_dirty_leb()' function with min_space =
wbuf->offs, so if it returns us an LEB, it is guaranteed to have at lease
'wbuf->offs' bytes of free+dirty space. So we can remove the subsequent code
which deals with "returned LEB has less than 'wbuf->offs' bytes of free+dirty
space". This simplifies 'ubifs_rcvry_gc_commit()' a little.
