tipc: Create helper routine to delete unused name sequence structure
Replaces two identical chunks of code that delete an unused name sequence structure from TIPC's name table with calls to a new routine that performs this operation. This change is cosmetic and doesn't impact the operation of TIPC. Signed-off-by: Allan Stephens <allan.stephens@windriver.com> Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com>
