lib/sort.c: fix kernel-doc notation warnings

Fix kernel-doc notation in lib/sort.c by using correct function parameter
names.

  lib/sort.c:59: warning: Excess function parameter 'size' description in 'swap_words_32'
  lib/sort.c:83: warning: Excess function parameter 'size' description in 'swap_words_64'
  lib/sort.c:110: warning: Excess function parameter 'size' description in 'swap_bytes'
