MIPS: futex: Restore \n after sync instructions
Commit 3c1d3f097972 ("MIPS: futex: Emit Loongson3 sync workarounds
within asm") inadvertently removed the newlines following
__WEAK_LLSC_MB, which causes build failures for configurations in which
__WEAK_LLSC_MB expands to a sync instruction:
{standard input}: Assembler messages:
{standard input}:9346: Error: symbol `sync3' is already defined
{standard input}:9380: Error: symbol `sync3' is already defined
...
Fix this by restoring the newlines to separate the sync instruction from
anything following it (such as the 3: label), preventing inadvertent
concatenation.
