Modified struct lu_dirpage in lustre_idl.h file to remove the sparse
warnings where cast to restricted types are made.
Following warnings are removed by this fix.

Isn't the below reason good enough?
Since the structure elements are always converted from little endian to processor native format
in mdc_request.c, struct lu_dirpage element types is modified.
