ARM: 8827/1: fix argument count to match macro definition

The macro str8w takes 10 arguments, abort being the 10th. In this
particular instantiation the abort argument is passed as 11th
argument leading to an error when using LLVM's integrated
assembler:
  <instantiation>:46:47: error: too many positional arguments
    str8w r0, r3, r4, r5, r6, r7, r8, r9, ip, , abort=19f
                                                ^
  arch/arm/lib/copy_template.S:277:5: note: while in macro instantiation
  18: forward_copy_shift pull=24 push=8
      ^

The argument is not used in the macro hence this does not change
code generation.
