Replace msleep() with fsleep() in rtw_cmd.c to improve delay
precision and follow modern kernel practices.

Specifically, this fixes a checkpatch warning for the 10ms delay
in _rtw_free_evt_priv() and updates the 100ms polling loops in
rtw_chk_hi_queue_hdl() and rtw_free_cmd_priv() for consistency.

Remove this.

Here's Dan Carpenters's resource on making a v2:

Having an extra --- cut off line doesn't matter.  The other thing that
you sometimes see is an extra blank line before the --- cut off line
and that's fine too.

Oh ok, nice to know. I guess I assumed the last cut of line was the one
that counted.
