Subject: [PATCH] libkmod-module: probe: fix infinite loop with softdeps
If a softdep depends on a module in the dependency list of the module
being inserted, we would enter and infinite loop.
Move the "mod->visited = true" assignment to the proper place, hoping it
didn't break other use cases. This is a bug that comes and goes every
now and then. Since we have a testsuite now, a test for this should be
written.
