usb: devio: remove assignment from if condition 

Fix five occurrences of the checkpatch.pl error:

ERROR: do not use assignment in if condition

The semantic patch that makes this change is:

// <smpl>
@@
identifier i;
expression E;
statement S1, S2;
@@

+ i = E;
  if (
- (i = E)
+ i
  ) S1 else S2

@@

statement S;
constant c;
binary operator b;
@@

+ i = E;
  if (
- (i = E)
+ i
  b
  c ) S
