media: c8sectpfe: Call of_node_put(i2c_bus) only once in c8sectpfe_probe()

[ Upstream commit b773530a34df0687020520015057075f8b7b4ac4 ]

An of_node_put(i2c_bus) call was immediately used after a pointer check
for an of_find_i2c_adapter_by_node() call in this function implementation.
Thus call such a function only once instead directly before the check.

This issue was transformed by using the Coccinelle software.
