lib: sbi_hsm: Put the resume_pending hart in the interruptible hart mask

Current interruptible hart mask doesn't include the hart which HSM state
is SBI_HSM_STATE_RESUME_PENDING. So when there is a request to send an
IPI to the hart which is in the resume process, this hart would miss the
IPI forever. Put the SBI_HSM_STATE_RESUME_PENDING hart in the
interruptible hart mask to fix the issue.
