f2fs: Fix root reserved on remount
On a remount, you can currently set root reserved if it was not
previously set. This can cause an underflow if reserved has been set to
a very high value, since then root reserved + current reserved could be
greater than user_block_count. inc_valid_block_count later subtracts out
these values from user_block_count, causing an underflow.
