i2c-dev: don't get i2c adapter via i2c_dev
commit 5136ed4fcb05cd4981cc6034a11e66370ed84789 upstream.
There is no code protecting i2c_dev to be freed after it is returned
from i2c_dev_get_by_minor() and using it to access the value which we
already have (minor) isn't safe really.
Avoid using it and get the adapter directly from 'minor'.
