[ Upstream commit a85c5c7a3aa8041777ff691400b4046e56149fd3 ]
The PM reference count is not expected to be incremented on
return in xiic_xfer and xiic_i2c_remove.
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.
Fixes: 10b17004a74c ("i2c: xiic: Fix the clocking across bind unbind")
