[PATCH] spi: img-spfi: fix reference leak in img_spfi_resume

[Zhang Qilong <zhangqilong3@xxxxxxxxxx>]

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

Fixes: deba25800a12b ("spi: Add driver for IMG SPFI controller")
