UBIFS: fix lprops committing bug
When writing lprop nodes, do not forget to set @from to 0 when
switching the LEB. This fixes the following bug:
UBIFS error (pid 27768): ubifs_leb_write: writing -15456 bytes at 16:15880, error -22
UBIFS error (pid 27768): do_commit: commit failed, error -22
UBIFS warning (pid 27768): ubifs_ro_mode: switched to read-only mode, error -22
Pid: 27768, comm: freespace Not tainted 2.6.29-rc4-ubifs-2.6 #43
