[PATCH v1 13/34] qemuDomainNamespaceMknodPaths: Turn @paths into string list

[Michal Privoznik]

Every caller does the same - counts the number of items in a
string list they have, only to pass the number to
qemuDomainNamespaceMknodPaths(). This is needless - the function
can accept the string list and count the items itself.
