net: ipa: use a bitmap for endpoint replenish_enabled

commit c1aaa01dbf4cef95af3e04a5a43986c290e06ea3 upstream.

Define a new replenish_flags bitmap to contain Boolean flags
associated with an endpoint's replenishing state.  Replace the
replenish_enabled field with a flag in that bitmap.  This is to
prepare for the next patch, which adds another flag.
