libdw: Add missing size check to parse_eh_frame_hdr.

afl-fuzz showed that when parse_eh_frame_hdr was called from
getcfi_scn_eh_frame invalid data could be read because of a missing size
check. That check was there when parse_eh_frame_hdr was called from
getcfi_gnu_eh_frame. Move the size check into parse_eh_frame. And add
an extra check to make sure d_buf is not NULL.
