target/riscv: Fix checking of whether instruciton at 'pc_next' spans pages

This bug has a noticeable behavior of falling back to the main loop and
respawning a redundant translation block including a single instruction
when the end address of the compressive instruction is exactly on a page
boundary, and slows down running system performance.
