__pcpu_balance_workfn() became fairly big and hard to follow, but in
fact it consists of two fully independent parts, responsible for
the destruction of excessive free chunks and population of necessarily
amount of free pages.
In order to simplify the code and prepare for adding of a new
functionality, split it in two functions:
1) pcpu_balance_free,
2) pcpu_balance_populated.
Move the taking/releasing of the pcpu_alloc_mutex to an upper level
to keep the current synchronization in place.
