UBIFS: introduce a separate structure for budgeting info
This patch separates out all the budgeting-related information
from 'struct ubifs_info' to 'struct ubifs_budg_info'. This way the
code looks a bit cleaner. However, the main driver for this is
that we want to save budgeting information and print it later,
so a separate data structure for this is helpful.
This patch is a preparation for the further debugging output
improvements.
