Herbert Xu dd56c671cc af_key: Fix send_acquire race with pfkey_register ...

[ Upstream commit 7f57f8165c ]

The function pfkey_send_acquire may race with pfkey_register
(which could even be in a different name space).  This may result
in a buffer overrun.

Allocating the maximum amount of memory that could be used prevents
this.
