xfrm: security: iterate all, not inexact lists

Browse source

currently all non-socket policies are either hashed in the dst table,
or placed on the 'inexact list'.  When flushing, we first walk the
table, then the (per-direction) inexact lists.

When we try and get rid of the inexact lists to having "n" inexact
lists (e.g. per-af inexact lists, or sorted into a tree), this walk
would become more complicated.

Simplify this: walk the 'all' list and skip socket policies during
traversal so we don't need to handle exact and inexact policies
separately anymore.
