i2c: designware: Omit a variable reassignment in dw_i2c_plat_probe()

An error code was assigned to a variable and checked accordingly.
This value was passed to a dev_err_probe() call in an if branch.
This function is documented in the way that the same value is returned.
Thus delete a redundant variable reassignment.

The source code was transformed by using the Coccinelle software.
