iio: imu: inv_icm42607: restore runtime PM on system resume errors

Browse source

pm_runtime_force_suspend() leaves runtime PM disabled after it succeeds and
expects pm_runtime_force_resume() to restore runtime PM management during
system resume.

The resume callback returns early if enabling the vddio regulator or
synchronizing the register cache fails, skipping the matching
pm_runtime_force_resume() call. Runtime PM consequently remains disabled
after the system has resumed, so runtime autosuspend can no longer turn off
sensors enabled afterward.

Call pm_runtime_force_resume() on both error paths. Keep the first error as
the return value and report a runtime PM restore failure separately.
