Report pool suspended due to MMP
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.
