lxc: Avoid Coverity SIZEOF_MISMATCH

Commit id '692e9fac7' used virProcessSetNamespaces instead of inlining
the similar functionality; however, Coverity notes that the function
prototype expects a size_t value and not an enum and complains. So,
just typecast the enum as a size_t to avoid the noise.
