RAND_bytes return value

[Steve G]

Hello,

I have been doing some looking at openssl 0.9.7 and
openssh3.5p1 and found a minor descrepancy. RAND_bytes() is
called around line 69 of openbsd-compat/bsd-arc4random.c.
It checks to see if the return is not zero. The RAND_bytes
function can also return -1, too. All the code in openssl
uses <=0 for the test rather than !. 

Best Regards,
Steve Grubb
