Subject: [PATCH 199/204] riscv: Add return value to check_unaligned_access().

The stable backport of commit c20d36cc2a207 ("riscv: don't probe
unaligned access speed if already done") added a `return' stament to
check_unaligned_access(). The return value of the function is `void' but
the RT tree has the backport of commit 73cf6167ef44c ("RISC-V: Probe
misaligned access speed in parallel") which changes the return type to
`int'.

Make the return statement return 0.
