f2fs: fix wrong error injection path in inc_valid_block_count()
If FAULT_BLOCK type error injection is on, in inc_valid_block_count() we may decrease sbi->alloc_valid_block_count percpu stat count incorrectly, fix it. Fixes: 36b877af7992 ("f2fs: Keep alloc_valid_block_count in sync") Signed-off-by: Chao Yu <yuchao0@huawei.com> Signed-off-by: Jaegeuk Kim <jaegeuk@kernel.org>
