[PATCH] Fix structure clearance in openssh_read()

[Christian Engelmayer]

When clearing the memory of 'key' in function openssh_read(), only the size
of the pointer to the data instead of the whole size of struct openssh_key
is cleared. Correct the size calculation as detected by Coverity CID 1191543.
