Subject: [PATCH] tlan: Fix two regressions introduced by 64bit conversion.

Two regressions were introduced by the recent tlan: 64bit conversion
commit (93e16847c9db0093065c98063cfc639cdfccf19a).  The first in
TLan_GetSKB caused a NULL pointer dereference.  With the second causing
the link to fail to come up.
