spi: spi-cadence-quadspi: Enable pm runtime earlier to avoid imbalance

The "probe_setup_failed" label calls pm_runtime_disable(), but
pm_runtime_enable() was placed after a possible jump to this label.
When cqspi_setup_flash() fails, control jumps to the label without
pm_runtime_enable() being called, leading to unbalanced PM runtime
reference counting.

Move pm_runtime_enable() and associated calls above the first
possible branch to "probe_setup_failed" to ensure balanced
enable/disable calls across all error paths.
