Place the call to pccard_insert_beep() in the inserted() timeout

Browse Source 
routine instead of pccard_event(). This avoids spurious extra calls
to pccard_insert_beep() at insert or remove time which could occur
due to noise on the card-present lines.

Clean up some code in pccard_beep.c; we were depending on the order
of evaluation of function arguments, which is undefined in C. Also,
use `0' rather than `NULL' for integer values.
