[VPP-1682] the 'curr_key' and 'next_key' members of struct 'bfd_session_t' could become wild pointer

[vvalderrv]

Description

the function 'bfd_auth_set_key' uses 'pool_get' to get a memory address 'auth_key', then in function 'bfd_auth_activate' , the 'auth_key' pointer  is assigned to 'bs->auth.next_key' or 

'bs->auth.curr_key'. However, when uses 'pool_get' to add a new bfd key, '_vec_resize' could change the pool start address, which will makes the 'bs->auth.next_key' or 'bs->auth.curr_key'

becoming unsaved pointer.
