[PATCH 4/4] spi: qcom-geni: fix sticky -EINVAL after PM runtime resume failure

[Praveen Talari]

PM_RUNTIME_ACQUIRE_IF_ENABLED() in spi_geni_init() calls
pm_runtime_resume_and_get() internally. When the resume callback
fails (e.g. -ETIMEDOUT), the RPM core sets power.runtime_error on
the device. Every subsequent PM_RUNTIME_ACQUIRE call then returns
-EINVAL immediately without attempting the resume, permanently
blocking the driver even though the underlying error may be transient.

Add pm_runtime_set_suspended() on the failure path to clear
power.runtime_error, allowing the next attempt to re-enter the
resume callback rather than failing immediately with -EINVAL.
