The assignment of -EINVAL to variable ret is redundant as it
is being overwritten on the following error exit paths or
to the return value from the following call to basic_set_parms.
Fix this up by removing it. Cleans up clang warning message:
net/sched/cls_basic.c:185:2: warning: Value stored to 'err' is never read
