Input: aiptek - validate raw macro indices before updating state

aiptek_irq() derives macro key indices directly from tablet reports and
then uses them to index macroKeyEvents[]. Report types 4 and 5 also save
the derived value in aiptek->lastMacro and later use that state to
release the previous key.

Validate the raw macro index once before it enters that state machine, so
lastMacro only ever stores an in-range macro key. Keep direct bounds
checks for report type 6, which reads the macro number from the packet
body and uses it immediately.
