i2c: img-scb: fix reference leak when pm_runtime_get_sync fails
The PM reference count is not expected to be incremented on
return in functions img_i2c_xfer and img_i2c_init.
However, pm_runtime_get_sync will increment the PM reference
count even failed. Forgetting to putting operation will result
in a reference leak here.
Replace it with pm_runtime_resume_and_get to keep usage
counter balanced.
