Revert "swiotlb: panic if nslabs is too small"

Browse source

This reverts commit 0bf28fc40d.

Reasons:
  1. new panic()s shouldn't be added [1].
  2. It does no "cleanup" but breaks MIPS [2].

v2: properly solved the conflict [3] with
commit 20347fca71 ("swiotlb: split up the global swiotlb lock")
