Fix RecycledLists size on Unix

The list size was set to g_SystemInfo.dwNumberOfProcessors which is a
number of processors the current process is allowed to run on, but not
the total number of processors in the system. Fixed to use
PAL_GetTotalCpuCount.

Also revert a change to the mbind node mask length computation I've
incorrectly made in my last commit and make it clear that the value is
a number of used bits in the node mask, which is the highest numa node
plus 1. And finally, re-reading the mbind doc, I've found that the
maxnode parameter is in fact "number of nodes" in the mask, so fixing
that too.
