Don't assume the type we read was the type we expected
i2v_GENERAL_NAME and GENERAL_NAME_print were assuming that the type of of a GENERAL_NAME (OTHERNAME) that we read in was the type we expected it to be. If its something else then this can cause unexpected behaviour. In the added fuzz test case an OOB read was occurring. This issue was recently added by commit 4baee2d.
