Vasily Gorbik aa4e460f09 lib/crc32test: remove extra local_irq_disable/enable
Commit 4d004099a6 ("lockdep: Fix lockdep recursion") uncovered the
following issue in lib/crc32test reported on s390:

  BUG: using __this_cpu_read() in preemptible [00000000] code: swapper/0/1
  caller is lockdep_hardirqs_on_prepare+0x48/0x270
  CPU: 6 PID: 1 Comm: swapper/0 Not tainted 5.9.0-next-20201015-15164-g03d992bd2de6 #19
  Hardware name: IBM 3906 M04 704 (LPAR)
  Call Trace:
    lockdep_hardirqs_on_prepare+0x48/0x270
    trace_hardirqs_on+0x9c/0x1b8
    crc32_test.isra.0+0x170/0x1c0
    crc32test_init+0x1c/0x40
    do_one_initcall+0x40/0x130
    do_initcalls+0x126/0x150
    kernel_init_freeable+0x1f6/0x230
    kernel_init+0x22/0x150

  no locks held by swapper/0/1.

Remove extra local_irq_disable/local_irq_enable helpers calls.

Fixes: 5fb7f87408 ("lib: add module support to crc32 tests")
