iommupt: Avoid a compiler bug with sw_bit
gcc 13, in some cases, gets confused if the __builtin_constant_p() is
inside the switch. It thinks that bitnr can have the value max+1 and
fails. Lift the check outside the switch to avoid it.
Fixes: ef7bfe5bbffd ("iommupt/x86: Support SW bits and permit PT_FEAT_DMA_INCOHERENT")
Fixes: 5448c1558f60 ("iommupt: Add the Intel VT-d second stage page table format")
