[PATCH] f2fs: fix wrong .available_nid calculation

[Chao Yu]

In mkfs, we have counted quota file's node number in cp.valid_node_count,
so we have to avoid wrong substraction of quota node number in
.available_nid calculation.

f2fs_write_check_point_pack()
{
..
	set_cp(valid_node_count, 1 + c.quota_inum + c.lpf_inum);

Fixes: 292c196a3695f2fs ("reserve nid resource for quota sysfile")
