When the pool is suspended, record whether it was due to an I/O error or due to MMP writes failing to succeed within the required time. Change spa_suspended from uint8_t to zio_suspend_reason_t to store the reason. When userspace queries pool status via spa_tryimport(), report the reason the pool was suspended in a new key, ZPOOL_CONFIG_SUSPENDED_REASON. In libzfs, when interpreting the returned config nvlist, report suspension due to MMP with a new pool status enum value, ZPOOL_STATUS_IO_FAILURE_MMP. In status_callback(), which generates and emits the message when 'zpool status' is executed, add a case to print an appropriate message for the new pool status enum value.
