UBIFS: fix inode size debugging check failure
This patch fixes a problem with the following symptoms:
UBIFS: deferred recovery completed
UBIFS error (pid 15676): dbg_check_synced_i_size: ui_size is 11481088, synced_i_size is 11459081, but inode is clean
UBIFS error (pid 15676): dbg_check_synced_i_size: i_ino 128, i_mode 0x81a4, i_size 11481088
It happens when additional debugging checks are enabled and we are recovering
from a power cut. When we fixup corrupted inode size during recovery, we change
them in-place and we change ui_size as well, but not synced_i_size, which
causes this failure. This patch makes sure we change both fields and fixes the
issue.
