[LTP] [PATCH] tst_af_alg: Fix control buffer memory leak

[Andrea Cervesato]

From: Andrea Cervesato <andrea.cervesato@suse.com>

The ancillary control buffer allocated in tst_alg_sendmsg() is never
freed after sendmsg(), leaking memory on repeated calls in the same
process.

Free the buffer once sendmsg() completes.
