Rémi Denis-Courmont 7591eb4055 Revert "lavc/sbrdsp: R-V V neg_odd_64" 
While this function can easily be written with vectors, it just fails to
get any performance improvement.

For reference, this is a simpler loop-free implementation that does get
better performance than the current one depending on hardware, but still
more or less the same metrics as the C code:

 func ff_sbr_neg_odd_64_rvv, zve64x
         li      a1, 32
         addi    a0, a0, 7
         li      t0, 8
         vsetvli zero, a1, e8, m2, ta, ma
         li      t1, 0x80
         vlse8.v v8, (a0), t0
         vxor.vx v8, v8, t1
         vsse8.v v8, (a0), t0
         ret
 endfunc
