x86/HVM: make hvmemul_map_linear_addr() honor p2m_ioreq_server

Write accesses to p2m_ioreq_server pages should get redirected to the
emulator also when using the mapping approach. Extend the
p2m_is_discard_write() check there, and restrict both to the write
access case (this is just a latent bug as currently we go this route
only for write accesses).
