Peter Mitsis 1b49cd2551 kernel: pipes: ISRs use a private pipe descriptor 
Fixes sporadic data access violations that were occuring when pipes
were being used from an ISR. The ISR was incorrectly using the pipe
descriptor belonging to the interrupted thread. This led to corrupted
pipe meta-data. The solution proposed here is to perform a run-time
check and if use a pipe descriptor on the ISR's stack if called from
an ISR.
