gpg: Initialize a parameter to silence valgrind.
* g10/keygen.c (read_parameter_file): Initialize nline. * g10/textfilter.c (copy_clearsig_text): Initialize bufsize.
In iobuf_read_line the parameter to pass and return the current buffer
length is controlled by the buffer parameter. Thus there should be no
problem because the assert call check s buffer first. For yet unknown
reasons when using the standard GNU libc assert valgrind complains
about an uninitialized variable. That does not happen with our
log_assert.
Tested with gnupg 2.2.23 with gcc 8.3.0 and valgrind 3.14.0.
