This series replaces two semaphores with three completion variables
in rtw_cmd_thread(). Completions variables are better suited for the
purposes that are explained in detail in the commit messages of patches
1/3 and 2/3. Furthermore, patch 3/3 removes a redundant 'if' statement
from that same rtw_cmd_thread().

Tested with ASUSTek Computer, Inc. Realtek 8188EUS [USB-N10 Nano]

Many thanks to Dan Carpenter [off-list ref] who helped with
his review of the RFC Patch.

v2 => v3:
	Patch 1/3:
		No changes;
	Patch 2/3:
		No changes;
	Patch 3/3:
		Furher process the commit message according to a review
		by Greg Kroah-Hartman [off-list ref]>.

v1 => v2:
        Patch 1/3: 
		No changes;
        Patch 2/3: 
		Replace wait_for_completion_killable() with
		wait_for_completion() because killing the kthread is
                not allowed and so there is no need for killable
                wait;
        Patch 3/3: 
		No changes.
