multipath: set ACT_RESIZE when the size has changed
 
When the multipath path devices change size, multipath can't be reloaded
with noflush set. So, don't set the action to ACT_RELOAD, which will
cause the multipath device to get stuck in SUSPEND. Use ACT_RESIZE.

Also, I was seeing some messages that were getting cut off with the
128 byte messages size, so I doubled that, and the log area size.
