i2c: qcom-cci: don't delete an unregistered adapter
commit a0d48505a1d68e27220369e2dd1e3573a2f362d2 upstream.
If i2c_add_adapter() fails to add an I2C adapter found on QCOM CCI
controller, on error path i2c_del_adapter() is still called.
Fortunately there is a sanity check in the I2C core, so the only
visible implication is a printed debug level message:
i2c-core: attempting to delete unregistered adapter [Qualcomm-CCI]
Nevertheless it would be reasonable to correct the probe error path.
Fixes: e517526195de ("i2c: Add Qualcomm CCI I2C driver")
