schematic: mark R24 as no place

R24 is pulling the voltage regulator output for VCC_SIM down.
it has probably been added at the same time as R15.
since we don't read VCC_SIM it is not important to have it in a
defined state.
also the card, phone, or simtrace will provide power to the card
when required (else the card load is high enough to immediately
pull it down).

this change has been tested with a real simtrace device.
trace and card emulation worked with a Nokia 3310.
