arm64: jump_label.h: use asm_volatile_goto macro instead of "asm goto"

[ Upstream commit 13aceef06adfaf93d52e01e28a8bc8a0ad471d83 ]

All other uses of "asm goto" go through asm_volatile_goto, which avoids
a miscompile when using GCC < 4.8.2. Replace our open-coded "asm goto"
statements with the asm_volatile_goto macro to avoid issues with older
toolchains.
