[PATCH 1/2] qemu: Fix CLang build
Commit f0169f4d caused a build failure with CLang due to potentially
uninitialized variable
../src/qemu/qemu_migration_params.c:825:17: error: variable 'nchannels'
is used uninitialized whenever '&&' condition is false
[-Werror,-Wsometimes-uninitialized]
825 | if (params && virTypedParamsGetInt(params, nparams,
| ^~~~~~
../src/qemu/qemu_migration_params.c:830:17: note: uninitialized use occurs here
830 | if (nchannels < 1) {
| ^~~~~~~~~
Initialize the number of channels to 1, the default value when the
number of channels is not specified.

Is it valid to specify '--parallel' without '--parallel-channels'? If so,
should the number of channels default to 1?
