locking: Fix qspinlock/x86 inline asm error

locking: Fix qspinlock/x86 inline asm error

When compiling linux 6.1.0-rc3 configured with CONFIG_64BIT=y and
CONFIG_PARAVIRT_SPINLOCKS=y on x86_64 using LLVM 11.0, an error:
"<inline asm> error: changed section flags for .spinlock.text,
expected:: 0x6" occurred.

The reason is the .spinlock.text in kernel/locking/qspinlock.o
is used many times, but its flags are omitted in subsequent use.

LLVM 11.0 assembler didn't permit to
leave out flags in subsequent uses of the same sections.

So this patch adds the corresponding flags to avoid above error.
