The inotify limits are per user, so another program can exhaust them and make InotifyInit1 or InotifyAddWatch fail. That aborted RunGame with "gamepad: InotifyAddWatch failed: no space left on device" even though inotify is only used to detect hotplugged gamepads. GLFW ignores these errors, so do the same and keep the gamepads found by the initial scan. Closes #3304
