Ard Biesheuvel 335ebe3035 lib/raid6: arm: optimize away a mask operation in NEON recovery routine 
The NEON recovery code was modeled after the x86 SIMD code, and for
some reason, that code uses a 16 bit wide signed shift and a mask to
perform what amounts to a 8 bit unsigned shift. So fold the ops
together.
