kunit/usercopy: Disable u64 test on 32-bit SPARC
[ Upstream commit 0d6efa20e384a41a7f4afdcd8a0aec442c19d33e ]
usercopy of 64 bit values does not work on 32-bit SPARC:
# usercopy_test_valid: EXPECTATION FAILED at lib/tests/usercopy_kunit.c:209
Expected val_u64 == 0x5a5b5c5d6a6b6c6d, but
val_u64 == 1515936861 (0x5a5b5c5d)
0x5a5b5c5d6a6b6c6d == 6510899242581322861 (0x5a5b5c5d6a6b6c6d)
Disable the test.
Fixes: 4c5d7bc63775 ("usercopy: Add tests for all get_user() sizes")
