Staging: winbond: wb35reg.c Coding style fixes

I fixed the problems reported by checkpatch.pl excetp for
long lines, a couple of printks and some warnings about usb_free_urb(NULL).
I checked for regressions with Dan Carpenters strip_whitespace.pl
and diff and everything looks good.
Generated .o is identical to master.

This is a new patch against master where I fixed up a switch-statement
after comments from Pavel Machek.
