i386: hvf: Don't miss 16-bit displacement
In 16-bit addressing mode, when Mod = 0 and R/M = 6, decoded displacement
doesn't reach decode_linear_addr and gets lost. Instructions that
involve the combination of ModRM always get a pointer with zero offset
from the beginning of DS segment.
The change fixes drawing in F-BIRD from day 1 of '18 advent calendar.
