tipc: use consistent GFP flags
Some functions, like tipc_crypto_start use inconsisten GFP flags
when allocating memory. The mentioned function use GFP_ATOMIC to
to alloc a crypto instance, and then calls alloc_ordered_workqueue()
which allocates memory with GFP_KERNEL. tipc_aead_init() function
even uses GFP_KERNEL and GFP_ATOMIC interchangeably.
No doc comment specifies what context a function is designed to
work in, but the flags should at least be consistent within a function.
