riscv: use local label names instead of global ones in assembly 
Local labels should be prefix by '.L' or they'll be exported in the
symbol table. Additionally, this messes up the backtrace by displaying
an incorrect symbol:

  ...
  [   12.751810] [<ffffffff80441628>] _copy_from_user+0x28/0xc2
  [   12.752035] [<ffffffff800152ca>] handle_misaligned_load+0x1ca/0x2fc
  [   12.752310] [<ffffffff80a033e8>] do_trap_load_misaligned+0x24/0xee
  [   12.752596] [<ffffffff80a0dcae>] _new_vmalloc_restore_context_a0+0xc2/0xce

After:
  ...
  [   10.243916] [<ffffffff804415e4>] _copy_from_user+0x28/0xc2
  [   10.244026] [<ffffffff800152ca>] handle_misaligned_load+0x1ca/0x2fc
  [   10.244150] [<ffffffff80a033a0>] do_trap_load_misaligned+0x24/0xee
  [   10.244268] [<ffffffff80a0dc66>] handle_exception+0x146/0x152
