net: sctp: prevent writes to cookie_hmac_alg from accessing invalid memory
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.
Fixes: 3c68198e7 ("sctp: Make hmac algorithm selection for cookie generation dynamic")
