keymap: continue reading keymap after invalid scancodes

Browse Source 
Reading of keymaps is aborted when EINVAL is returned from EVIOCGETKEYCODE.
Scan codes are not always continuous ranges of values starting at 0, so this
can result in not getting the full keymap for a device. Instead, continue
processing if EINVAL is returned.
