[PATCH] staging: r8188eu: Use flexible-array for one length array member

[Deepak R Varma <drv@mailo.com>]

Flexible-array member should be used instead of one or zero member to
meet the need for having a dynamically sized trailing elements in a
structure. Refer to links [1] and [2] for detailed guidance on this
suggestion.
