free error message when freeing context

Call krb5_clear_error_message() to free any allocated error message
before freeing the context.

The condition that triggered this was a plugin library which fails to
load because of unresolved references.  It appears dlopen() on Linux
leaks four bytes for each failing library in this situation.
