[PATCH] drm/amdkfd: Fix MEC pipe interrupt enablement

[Lijo Lazar]

for_each_inst modifies xcc_mask and therefore the loop doesn't
initialize properly interrupts on all pipes. Keep looping through xcc as
the outer loop to fix this issue.

Fixes: 7b04c90a48b1 ("drm/amdkfd: Use xcc mask for identifying xcc")
