Current checkpatch implementation permits notation like:
} else{
in kernel code.
It looks like oversight and inconsistency in checkpatch rules (e.g.
instruction like 'do' is tested).
Add regex for checking space after 'else' keyword and trigger error if
space is not present.

Thanks.
btw: the fix block blow also should be updated with else
