Export correct symbols for Lustre Direct I/O

Browse Source 
Originally the Lustre ZFS OSD code was going to use zfs_uio_t structs
for supporting Direct I/O with ZFS. However, this has changed to using
abd_t structs instead. This exports the proper symbols that will be used
by the Lustre ZFS OSD code.
