Subject: [PATCH] UT: Fix valgrind failure in SPDK UT on arm64 system

When ran SPDK UT on arm64 system, observerd the valgrind fault:

ARM64 front end: branch_etc
disInstr(arm64): unhandled instruction 0xD5380000
disInstr(arm64): 1101'0101 0011'1000 0000'0000 0000'0000
==959274== valgrind: Unrecognised instruction at address 0x4014c90.

It is because that arm64 is not supported completly in the latest
valgrind release v3.13.0.

With the patch, SPDK UT can run successfully on arm64 system.
