Leo Yan d18c882f85 perf tools: Fix compilation error on arm64 
Since the commit dc6d2bc2d8 ("perf sample: Make user_regs and
intr_regs optional"), the building for Arm64 reports error:

arch/arm64/util/unwind-libdw.c: In function ‘libdw__arch_set_initial_registers’:
arch/arm64/util/unwind-libdw.c:11:32: error: initialization of ‘struct regs_dump *’ from incompatible pointer type ‘struct regs_dump **’ [-Werror=incompatible-pointer-types]
   11 |  struct regs_dump *user_regs = &ui->sample->user_regs;
      |                                ^
cc1: all warnings being treated as errors
make[6]: *** [/home/niayan01/linux/tools/build/Makefile.build:85: arch/arm64/util/unwind-libdw.o] Error 1
make[5]: *** [/home/niayan01/linux/tools/build/Makefile.build:138: util] Error 2
arch/arm64/tests/dwarf-unwind.c: In function ‘test__arch_unwind_sample’:
arch/arm64/tests/dwarf-unwind.c:48:27: error: initialization of ‘struct regs_dump *’ from incompatible pointer type ‘struct regs_dump **’ [-Werror=incompatible-pointer-types]
   48 |  struct regs_dump *regs = &sample->user_regs;
      |                           ^

To fix the issue, use the helper perf_sample__user_regs() to retrieve
the user_regs.
