drm/xe/sync: Use for_each_tlb_inval() to calculate invalidation fences

Browse Source 
xe_sync_in_fence_get() uses the same kind of mismatched fence array
allocation vs looping logic that was previously noted and changed by
commit 0a4c2ddc71 ("drm/xe/vm: Use for_each_tlb_inval() to calculate
invalidation fences").  As with that commit, the mismatch doesn't cause
any problem at the moment since for_each_tlb_inval() loops the same
number of times as XE_MAX_GT_PER_TILE (2).  However we don't want to
assume that these will always be the same in the future, so switch to
using for_each_tlb_inval() in both places to future-proof the code.
