Subject: [RHEL7.7 PATCH 01/21] Assemble: keep MD_DISK_FAILFAST and

 MD_DISK_WRITEMOSTLY flag

Before updating superblock of slave disks, desired_state value

is set for the target state of the slave disks. But it forgets

to check MD_DISK_FAILFAST and MD_DISK_WRITEMOSTLY flags. Then

start_arrays() calls ADD_NEW_DISK ioctl-call and pass the state

without MD_DISK_FAILFAST and MD_DISK_WRITEMOSTLY.

Currenlty it does not generate any problem because kernel does not

care MD_DISK_FAILFAST or MD_DISK_WRITEMOSTLY flags.
