IB/qib: fix test of unsigned variable
Commit d4988623cc60 ("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.
