ubifs: ubifs_jnl_change_xattr: Remove assertion 'nlink > 0' for host inode
Changing xattr of a temp file will trigger following assertion failed
and make ubifs turn into readonly filesystem:
ubifs_assert_failed [ubifs]: UBIFS assert failed: host->i_nlink > 0,
in fs/ubifs/journal.c:1801
Reproducer:
1. fd = open(__O_TMPFILE)
2. fsetxattr(fd, key, value2, XATTR_CREATE)
3. fsetxattr(fd, key, value2, XATTR_REPLACE)
Fix this by removing assertion 'nlink > 0' for host inode.
