[PATCH] libertas: revert CAPINFO_MASK to its original value

CAPINFO_MASK changed on commits 981f187b and a091095b. Reverting to the original
value.  Also move CAPINFO_MASK into the sole user, join.c.  CAPINFO_MASK
should be in host CPU byte order; capability is converted to device
byte order elsewhere.

This fixes OLPC ticket #2161
