meta-facebook: yosemite4: state: Fix missing return code in power-cmd

The gpio_get(), gpio_set(), and get_ac_on_status() functions in
power-cmd only used echo to indicate failure without returning a
non-zero exit code. Since echo always succeeds (returns 0), all callers
using 'if !' to check the return code could never reach their error
handling paths.

Add 'return 1' after the failure echo in each function so that callers
such as chassis-powercycle, chassis-poweroff, and chassis-poweron can
properly detect and handle GPIO operation failures.
