USB: EHCI: Rearrange create_companion_file() to avoid GCC-4.6 warnings.

Browse source

In create_companion_file() there is a bogus assignemt to i created for
the express purpose of avoiding an ignored return value warning.

With pre-release GCC-4.6, this causes a 'set but not used' warning.

Kick the problem further down the road by just returning i.  All the
callers of create_companion_file() ignore its return value, so all is
good:

o No warnings are issued.

o We still subvert the desires of the authors of device_create_file()
  by ignorning error conditions.
