[PATCH v2 33/50] wilc1000: move ac_desired_ratio calculation to where its needed

[David Mosberger-Tang <davidm@xxxxxxxxxx>]

Move ac_desired_ratio calculation to fill_vmm_table() since that's the
only place that needs it.  Note that it is unnecessary to initialize
the array since ac_balance() is guaranteed to fill it in.
