USB: fix limited_power setting mistake in hub.c

This patch (jx001) fixes a variable assignment mistake in hub driver.
limited_power should be set to 0 if the hub is self-powered,and 1 if
the hub is bus-powered.

However, the effect of the code was exactly opposite to the spec's
statement for the Local Power Source field. The spec says, this field
is 1 meaning Local power supply lost while this field is 0 indicating
Local power supply good.(This statement is very confusing.)

So this patch switchs the 0 and 1.
