ARM: kprobes: Reject 16-bit Thumb SETEND, CPS and BKPT instructions

Browse source

These are very rare and/or problematic to emulate so we will take the
easy option and disallow probing them (as does the existing ARM
implementation).

Rejecting these instructions doesn't actually require any entries in the
decoding table as it is the default case for instructions which aren't
found.
