spi: tegra114: fix reference leak in tegra spi ops
[ Upstream commit a042184c7fb99961ea083d4ec192614bec671969 ]
pm_runtime_get_sync will increment pm usage counter even it
failed. Forgetting to pm_runtime_put_noidle will result in
reference leak in two callers(tegra_spi_setup and
tegra_spi_resume), so we should fix it.
