checkpatch: check for space after "else" keyword
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.
