tools: kwboot: Fix quitting terminal
Sometimes kwboot after quitting terminal prints error message:
terminal: Bad address
This is caused by trying to call write() syscall with count of (size_t)-1
bytes.
When quit sequence is split into more read() calls then number of input
bytes (nin) at the end of cycle can underflow and be negative. Fix it.
