arm: hevc_qpel: Fix the assembly to work with non-multiple of 8 widths

Browse Source 
This unbreaks the fate-checkasm-hevc_pel test on arm targets.

The assembly assumed that the width passed to the DSP functions is
a multiple of 8, while the checkasm test used other widths too.

This wasn't noticed before, because the hevc_pel checkasm tests
(that were added in 9c513edb79 in
January) weren't run as part of fate until in
b492cacffd in August.

As this hasn't been an issue in practice with actual full decoding
tests, it seems like the actual decoder doesn't call these functions
with such widths. Therefore, we could alternatively fix the test
to only test things that the real decoder does, and this modification
could be reverted.
