m25p80.c: Return state to IDLE after COLLECTING

state. For a well behaved guest this patch has no consequence, but
A bad guest could crash QEMU by using one of the erase commands
followed by a longer than 5 byte argument (undefined behaviour)....

m25p80: Support for Quad SPI

Added the Quad mode read and write commands. Data remains serialized on a
single wire, i.e. the quad mode instructions just behave the same as single
