f2fs: reject invalid recovered filename lengths

Browse source

Recovery uses raw_inode->i_namelen directly when rebuilding fsynced
dentries. A zero-length name uses no dentry slots, so recovery can
report success without recreating the dentry.

Treat zero-length and oversized recovered names as corruption, mark
NEED_FSCK, and stop recovery with -EFSCORRUPTED.
