[PATCH 2/3] mm/tlb: Fix wrong judgement in allocate_global_asid()

[Hou Wenlong]

In allocate_global_asid(), 'global_asid_available' cannot be zero, as it
has already been checked in use_global_asid(). Therefore, the warning in
allocate_global_asid() cannot be triggered; fix the wrong judgment in
allocate_global_asid().

Fixes: d504d1247e36 ("x86/mm: Add global ASID allocation helper functions")
