Staging: rtl8192u: remove dead code to disable dot11d

This patch removes all the ENABLE_DOT11D ifdefs.
It is always defined for driver. DOT11D has to do with regulatory domains.

What prompted this patch was a warning message in Sparse.

drivers/staging/rtl8192u/r8192U_core.c:247:1: warning: "eqMacAddr"
redefined in file included from drivers/staging/rtl8192u/:81:81:
drivers/staging/rtl8192u/dot11d.h:35:1: warning: this is the location
of the previous definition

Now there are no ifdefs around dot11d.h it made no sense to have this
second definition, so I removed that macro as well. ( Thanks Dan ;-) ).
