Xi: fix swapped grab mode args for keyboard devices in XIGrabDevice

Browse Source 
The protocol says that the grab_mode argument applies to the device
being grabbed and paired_device_mode to the paired master
device. GrabDevice() however takes in a pointer mode and a keyboard
mode and so we have to swap the values according the type of device
being grabbed.
