Herbert Xu 4625ee5acf af_key: Fix send_acquire race with pfkey_register 
[ Upstream commit 7f57f8165cb6d2c206e2b9ada53b9e2d6d8af42f ]

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.
