debugfs: fix printing of inline data during symlink inode dump
When we're dumping a fast symlink inode, we print some odd things to
stdout. To clean this up, first don't print inline data EA, since the
inode dump doesn't display file and directory contents. Then, teach
the inode dump function how to print out either an inline data fast
symlink or a non-inline data fast symlink.
(This is a follow-up to the earlier patch "debugfs: Only print the
first 60 bytes from i_block on a fast symlink")
[ Modified by tytso so that the d_inline_dump test works when build
directory is different from the source directory --- i.e., when
doing a VPATH build. ]
