spi: img-spfi: Fix pm_runtime_get_sync() error checking

Browse Source 
[ Upstream commit cc470d55343056d6b2a5c32e10e0aad06f324078 ]

If the device is already in a runtime PM enabled state
pm_runtime_get_sync() will return 1, so a test for negative
value should be used to check for errors.

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