staging: rtl8192u: clean up blank line style issues

Add missing and remove unnecessary blank lines to clear checkpatch
issues.

CHECK: Please use a blank line after function/struct/union/enum declarations
CHECK: Blank lines aren't necessary before a close brace '}'
CHECK: Please don't use multiple blank lines
CHECK: Blank lines aren't necessary after an open brace '{'
