Sasha Levin 8534537d0b net: sctp: prevent writes to cookie_hmac_alg from accessing invalid memory ...

[ Upstream commit 320f1a4a17 ]

proc_dostring() needs an initialized destination string, while the one
provided in proc_sctp_do_hmac_alg() contains stack garbage.

Thus, writing to cookie_hmac_alg would strlen() that garbage and end up
accessing invalid memory.
