arch: fe310: Fix mstatus handling

Browse source 
In previous commit, mstatus.mie was set when creating a new task
    but this change was incorrect and had a side effect such that
    a machine interrupt would be enabled just before returning from
    interrupt handling routine to switch context.

    Also, mstatus.mpp is set to machine mode in up_get_newintctx()
    instead of fe310_dispatch_irq().
