Fix arena_get() usage.

Browse Source 
Fix arena_get() calls that specify refresh_if_missing=false.  In
ctl_refresh() and ctl.c's arena_purge(), these calls attempted to only
refresh once, but did so in an unreliable way.
arena_i_lg_dirty_mult_ctl() was simply wrong to pass
refresh_if_missing=false.
