mm/page-writeback.c: Update comment for BANDWIDTH_INTERVAL

Browse Source 
The name of the BANDWIDTH_INTERVAL macro is misleading, as it is not
only used in the bandwidth update functions wb_update_bandwidth() and
__wb_update_bandwidth(), but also in the dirty limit update function
domain_update_dirty_limit().

Currently, we haven't found an ideal name, so update the comment only.
