Jeff Epler 46a58fb4b5 Early out of (un)maskInterrupts() if no GPIO interrupts need to be masked (#2831)
My application is designed to generate HSTX data on core0 in interrupts,
but also uses hardware SPI for SD card access.

It turns out that the amount of time spent in maskInterrupts/
unmaskInterrupts, even with an empty _usingIRQs, is too long.

Add a quick check and avoid touching the interrupt disable flag if
there's not actually any GPIO interrupt to (un)mask.
