qcacmn: Remove CONFIG_WIN from QDF sources

The qdf nbuf cb has members defined as union
which would be used separately either for WIN or MCL.
There are separate header files defined for having
different accessor functions for WIN or MCL.

The inclusion of the header file is differentiated
based on CONFIG_WIN which should be removed.

Use a different macro instead of CONFIG_WIN.
