iommufd: Make attach_handle generic than fault specific
commit fb21b1568adaa76af7a8c853f37c60fba8b28661 upstream.
"attach_handle" was added exclusively for the iommufd_fault_iopf_handler()
used by IOPF/PRI use cases. Now, both the MSI and PASID series require to
reuse the attach_handle for non-fault cases.
Add a set of new attach/detach/replace helpers that does the attach_handle
allocation/releasing/replacement in the common path and also handles those
fault specific routines such as iopf enabling/disabling and auto response.
This covers both non-fault and fault cases in a clean way, replacing those
inline helpers in the header. The following patch will clean up those old
helpers in the fault.c file.
