libpayload-x86: i8042: fix i8042_data_ready_ps2 and i8042_data_ready_aux
keyboard_disconnect was called without keyboard_init being called and in this
case keyboard_havechar returns true because i8042_data_ready_ps2 is
dereferencing uninitialized variable ps2_fifo from within fifo_is_empty causing
keyboard_disconnect to be stuck in this while loop.
while (keyboard_havechar())
keyboard_getchar();
BUG=b:80299098
TEST=Check if the normal mode path in depthcharge is not causing a hang
