Commit d4988623 ("IB/qib: use arch_phys_wc_add()") adjusted mtrr inititialization to use the new interface. Unfortunately, the new interface returns a signed value and the patch tested the unsigned wc_cookie. Fix the issue by changing the type of wc_cookie to int. For the success case the ret left at zero to avoid a warning from the caller. For failure wc_cookie is used as the ret.
