spi: spi-ti-qspi: fix reference leak in ti_qspi_setup

BugLink: https://bugs.launchpad.net/bugs/1910822
[ Upstream commit 45c0cba753641e5d7c3207f04241bd0e7a021698 ]

pm_runtime_get_sync will increment pm usage counter even it
failed. Forgetting to pm_runtime_put_noidle will result in
reference leak in ti_qspi_setup, so we should fix it.
