The original code is equivalent to:
wrqu->retry.flags = 0x1000 & 0x0002;
so it just sets .flags to zero. We should be ORing the values together
like r8192_wx_get_retry() does in drivers/staging/rtl8192u/r8192U_wx.c.

In drivers/staging/rtl8192e/rtllib_softmac.c::rtllib_rx_assoc_resp()
we allocate memory for 'network' with kzalloc() and then proceed to
zero the already zeroed mem we got from kzalloc() with
memset(). That's redundant, so remove the memset()
We also fail to kfree() the memory we allocated for 'network' if we do not enter
if (ieee->current_network.qos_data.supported == 1) {
and the variable then goes out of scope.
To fix that I simply moved the kfree() that was inside that 'if'
statement to instead be just after it. It then covers both the case
where we take the branch and when we don't.

Convert rtllib from registering the crypt drivers against rtllib_crypt
and instead register the against lib80211. The crypto functions have
R- prepended (R-CCMP, R-TKIP, R-WEP) so they will not clash with the
lib80211 versions.
We cannot use the lib80211 crypt drivers since the rtl8192e has some
hardware support that is not handled by the lib80211 crypt drivers.

Now that the rtl8192e driver is split up, it makes sense to keep the
rtllib code in one directory and the rtl8192e specific code in
another. This patch contains the split and the fixup of includes.
Since rtl_core.h already included rtllib.h and dot11d.h, rtl_core.h
was updated to point to the parent directory. All other references to
rtllib.h and dot11d.h in the rtl8192e specific code where deleted
rather than fixed. This leaves just one file that needs to know the
real location of the rtllib includes.
