Staging: rtl8192u: Fix space issues before '(' and after ')'

Space is required before the open and after the close parenthesis.
This patch adds space after 'if' and before '{'.

This was done with the help of the following Coccinelle script:

@r@
expression E;
position p1,p2,p3;
@@

if@p1 (E) @p3{@p2
        ...
}

@script:python@
p1 << r.p1;
p2 << r.p2;
p3 << r.p3;
@@

l1 = int (p1[0].line)
l2 = int (p2[0].line)
l3 = int (p3[0].line)
c1 = int (p1[0].column_end)
c2 = int (p2[0].column)
c3 = int (p3[0].column)
if (l1 != l2):
  cocci.include_match(False)
if (l2 == l3 and c3 + 2 == c2):
  cocci.include_match(False)
