Subject: [PATCH v1 2/5] riscv: Replace direct thread flag check with is_compat_task()
There is some code that detects compat mode into a task by checking the
flag directly, and other code that check using the helper is_compat_task().
Since the helper already exists, use it instead of checking the flags
directly.
