arm64: atomics: Remove '&' from '+&' asm constraint in lse atomics The lse implementation of atomic64_dec_if_positive uses the '+&' constraint, but the '&' is redundant and confusing in this case, since early clobber on a read/write operand is a strange concept. Replace the constraint with '+'. Signed-off-by: Will Deacon <will.deacon@arm.com>
