qcacmn: Remove obsolete g_qdf_trace_info infrastructure

The original version of the QDF trace functionality, introduced in
Change-Id I1d0cdfd8730a5c021aaa50b7dc8549d491d760b3, included a log
filtering mechanism inherited from the MCC code.  This mechanism used
an internal table g_qdf_trace_info along with the following APIs which
were used to configure and query the table:
- qdf_trace_set_level
- qdf_trace_set_module_trace_level
- qdf_trace_set_value
- qdf_trace_get_level

Subsequently, as part of the MCC/WIN QDF convergence project,
Change-Id I871c09189202d021405777db732e8821e7aaca7c ("qcacmn: Update
QDF Debug Framework") updated the QDF trace functionality, and as a
result the usage of the g_qdf_trace_info table was replaced.

Since the legacy infrastructure is no longer used, remove it.
