ath5k: disable MIB interrupts

upstream commit: 9ca9fb8aa8422595956af9681518cdb8b167055e

The MIB interrupt fires whenever counters overflow; however without
support for automatic noise immunity, we can sometimes get an interrupt
storm.  The get_stats() callback reads the counters anyway so we can
disable the interrupt for now until ANI is implemented.  This fixes
the issue reported in http://bugzilla.kernel.org/show_bug.cgi?id=12647.
