KVM: x86: Fix poll command
According to the hardware manual, when the Poll command is issued, the
byte returned by the I/O read is 1 in Bit 7 when there is an interrupt,
and the highest priority binary code in Bits 2:0. The current pic
simulation code is not implemented strictly according to the above
expression.
Fix the implementation of pic_poll_read(), set Bit 7 when there is an
interrupt.
