Ian Lance Taylor b0472e225b internal/poll: don't use r/w lock for Pread/Pwrite 
Since Pread/Pwrite specify a file offset, using incref is sufficient.
This permits multiple Pread/Pwrite calls in parallel.

Since Pread/Pwrite specify a file offset, it doesn't seem to make
sense to use the poller for them, so don't.

Updates #19586
