Also add new api to get time of the day in microseconds.

When switching from mission mode to FTM or Epping mode,
g_pktlog_pde is not cleared after de-init. When switching
back to mission mode, a warning is produced as the proc
directory is not found.
To fix this, g_pktlog_pde is cleared when pktlog is
de-initialized.

1. The logging macros implicitly takes care of embedding function name
in the log, hence there is no need to include __func__ again.
Getting rid of redundant __func__ reduces driver memory footprint.
2. Instead of adding __func__ to the qdf_nofl_* macros, its better to use
qdf_* which already takes care of adding __func__.

Protect pktlog funcitonality under given mutex to avoid possible
race condition between pktlog_release/pktlog_open and pktlogmod_exit.
Also call pktlogmod_exit before calling wdi_event_detach to avoid
accessing freed memory in pktlog release.

Replace printk with qdf_nofl_info in qdf folder.
So if we wish to change from printing on console
to other location, based on a logging daemon, we
can do that by only changing at the implementation
of QDF print API's

Per the Linux Kernel coding style, as enforced by the kernel
checkpatch script, pointers should not be explicitly compared to
NULL. Therefore within utils replace any such comparisons with logical
operations performed on the pointer itself.

4. Retain pktlog initial state
