ext4: Allow reading files with non-zero offset, clamp read len
Support was already implemented, but not hooked up. This fixes several
fails in the test cases.

ext4: Fix handling of direntlen in unlink_filename
The direntlen checks were quite bogus, i.e. the loop termination used
"len + offset == blocksize" (exact match only), and checked for a
direntlen less than 0. The latter can never happen as the len is
unsigned, this has been reported by Coverity, CID 153384.
Use the same code as in search_dir for directory traversal. This code
has the correct checks for direntlen >= sizeof(struct dirent), and
offset < blocksize.
