spi: img-spfi: fix reference leak in img_spfi_resume

Browse source 
[ Upstream commit ee5558a9084584015c8754ffd029ce14a5827fa8 ]

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: deba25800a ("spi: Add driver for IMG SPFI controller")
