knfsd: exportfs: remove iget abuse
When the exportfs interface was added the expectation was that filesystems
provide an operation to convert from a file handle to an inode/dentry, but it
kept a backwards compat option that still calls into iget.
Calling into iget from non-filesystem code is very bad, because it gives too
little information to filesystem, and simply crashes if the filesystem doesn't
implement the ->read_inode routine.
Fortunately there are only two filesystems left using this fallback: efs and
jfs. This patch moves a copy of export_iget to each of those to implement the
get_dentry method.
While this is a temporary increase of lines of code in the kernel it allows
for a much cleaner interface and important code restructuring in later
patches.
