linux-user: Check for bad event numbers in epoll_wait
The kernel checks that the maxevents parameter to epoll_wait
is non-negative and not larger than EP_MAX_EVENTS. Add this
check to our implementation, so that:
* we fail these cases EINVAL rather than EFAULT
* we don't pass negative or overflowing values to the
lock_user() size calculation
