spi: stm32-qspi: fix reference leak in stm32 qspi operations

Browse source

[ Upstream commit 88e1419b5e ]

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(stm32_qspi_exec_op and
stm32_qspi_setup), so we should fix it.
