i2c: cadence: fix reference leak when pm_runtime_get_sync fails

mainline inclusion
from mainline-v5.13-rc1
commit 23ceb846
category: bugfix
bugzilla: https://gitee.com/src-openeuler/kernel/issues/I94JHY
CVE: CVE-2020-36784

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=23ceb8462dc6f4b4decdb5536a7e5fc477cdf0b6



---------------------------

The PM reference count is not expected to be incremented on
return in functions cdns_i2c_master_xfer and cdns_reg_slave.

However, pm_runtime_get_sync will increment pm usage counter
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.
