Since commit df1404650ccb ("mac80211: remove support for IFF_PROMISC")
monitor mode for rt2x00 has been made effectively useless because the
hardware filter is configured to drop packets whose intended recipient is
not the device, regardless of the presence of monitor mode interfaces.
This patch fixes this regression by adding explicit monitor mode support,
and by configuring the hardware filter accordingly.

This code causes a static checker bug.
drivers/net/wireless/ralink/rt2x00/rt2500usb.c:232 _rt2500usb_register_read()
warn: passing casted pointer 'value' to 'rt2500usb_register_read()' 32 vs 16.
If the low 16 bits were initialized to zero then this code would only be
a problem on big endian systems. But in this case this is case the low
16 bits are never initialized. This is called from a function which is
created using a macro:
RT2X00DEBUGFS_OPS(csr, "0x%.8x\n", u32);
We end up copying uninitialized data to the user which is bogus and an
information leak.
