Revert "arm64: xchg: Fix compilation issue with __xchg_mb" 

This reverts commit cb2ddc73.

When clang enabled for arm64 architecture inline was not
always_iniline because CONFIG_OPTIMIZE_INLINING is not enabled.
Some code depends on that behavior of online means __always_inline
and check this link [1] for more information.
net/built-in.o: In function `__xchg_mb':
arch/arm64/include/asm/cmpxchg.h:99: undefined reference to
`__compiletime_assert_99'
arch/arm64/include/asm/cmpxchg.h:99: undefined reference to
`__compiletime_assert_99

To avoid compilations issues commit cb2ddc73 ("arm64: xchg:
Fix compilation issue with __xchg_mb") was introduced.
Recently upstream community made inline as __always_inline for arm64 as
well.
So reverting our downstream solution for above compilation issue.
