erofs-utils: update i_nlink stat for directories Previously, nlink of directories was treated as 1 for simplicity. Since st_nlink for dirs is actually not well defined, nlink=1 seems to pacify `find' (even without -noleaf option) and other utilities. AFAICT, isofs, romfs and cramfs always set it to 1, Overlayfs sets it to 1 conditionally, btrfs[1], ceph[2] and FUSE client historically set it to 1. The convention under unix is that it's # of subdirs including "." and "..". This patch tries to follow such convention if possible to optimize `find' performance since it's not quite hard for local fs.
