[PATCH v2 2/4] staging: r8188eu: convert rtw_is_cckrates_included() to bool

[Michael Straube]

Function rtw_is_cckrates_included() returns boolean values.
Change the return type to bool to reflect this.

Thanks for redoing the series as suggested by Joe Perches.
This is a perfect case where conciseness and readability don't clash and 
instead the former enhances the latter. 

Nice work, although you chose to not take Joe's suggestion about making a 
helper inline function. That would have been perfect, but I think it is a 
minor issue. So...

P.S.: If I were you, I'd have provided a cover letter that would have helped 
the readers to immediately understand the purpose of the entire series. I'm 
not sure whether or not the above-mentioned cover is a strict requirement.

Perhaps do the whole thing in one go (moving the & 0x7f into the helper
avoids an early loop exit defect when the rate being indexed is 0x80)
