Wang Li 4a01ad002d spi: fsl-lpspi: Fix PM reference leak in lpspi_prepare_xfer_hardware() 
[ Upstream commit a03675497970a93fcf25d81d9d92a59c2d7377a7 ]

pm_runtime_get_sync will increment pm usage counter even it failed.
Forgetting to putting operation will result in reference leak here.
Fix it by replacing it with pm_runtime_resume_and_get to keep usage
counter balanced.

Fixes: 944c01a889 ("spi: lpspi: enable runtime pm for lpspi")
