Subject: [PATCH 1/2] vfs: call file_ioctl call for directories.

Most of the ioctl callback in file_ioctl should be done even
for directories. For ext4 fiemap should work even for directories.
Similarly FIGETBSZ  should work for directories. For bmap filefrag command
doesn't do the ioctl if the type is not a regular file.
