i2c: stm32f7: fix reference leak when pm_runtime_get_sync fails
The PM reference count is not expected to be incremented on
return in these stm32f7_i2c_xx serious functions.
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.
