KVM: remove CAP_SYS_RAWIO requirement from kvm_vm_ioctl_assign_irq

Browse Source 
Remove this check in an effort to allow kvm guests to run without
root privileges.  This capability check doesn't seem to add any
security since the device needs to have already been added via the
assign device ioctl and the io actually occurs through the pci
sysfs interface.
