[cocci] [PATCH 32/36] USB: serial: ch341: remove conditional return with no effect

Both branches of the check return the same value, so the check has
no effect. Remove it and return the value directly.

This is the result of running the Coccinelle script from
scripts/coccinelle/misc/cond_return_no_effect.cocci.
