[PATCH] x86: bpf_jit_comp: simplify trivial boolean return

[Quentin Lambert <lambert.quentin@gmail.com>]

Remove if then else statements preceding
boolean return. Occurences were found using
Coccinelle.

The semantic patch used was:

@@
expression expr;
@@


- if ( expr )
-	return true;
- else
-	return false;
+ return expr;
