The verify_header() function has code that ensures all headers in a
single data chunk passed to aa_unpack() have the same namespace. The
value pointed by the ns argument is however unconditionally set to NULL
on each invocation to verify_header(). This effectively makes the code
that checks for namespace changes from one profile to another, dead
code.

Since the only caller, aa_unpack(), already initializes *ns = NULL the
redundant initialization in verify_header() can be safely dropped.
