Input: ibmasm - convert to dynamic input_dev allocation

Here is a fixed up patch that adds the mouse_dev = NULL to prevent freeing
memory twice.

Update the ibmasm driver to use the dynamic allocation of input_dev structs to
work with the sysfs subsystem.

Vernon: Added mouse_dev = NULL to error handling
Vojtech: Fixed some problems/bugs in the patch.
Dmitry: Fixed some more.
