md: use new apis to suspend array before mddev_create/destroy_serial_pool mddev_create/destroy_serial_pool() will be called from several places where mddev_suspend() will be called later. Prepare to remove the mddev_suspend() from mddev_create/destroy_serial_pool().

init: improve the name_to_dev_t interface name_to_dev_t has a very misleading name, that doesn't make clear it should only be used by the early init code, and also has a bad calling convention that doesn't allow returning different kinds of errors. Rename it to early_lookup_bdev to make the use case clear, and return an errno, where -EINVAL means the string could not be parsed, and -ENODEV means it the string was valid, but there was no device found for it. Also stub out the whole call for !CONFIG_BLOCK as all the non-block root cases are always covered in the caller.

md: return the allocated devices from md_alloc Two callers of md_alloc want to use the newly allocated devices, so return it instead of letting them find it cumbersomely after the allocation.

md: Explicitly create command-line configured devices Boot-time assembly of arrays with md= command-line arguments breaks when CONFIG_BLOCK_LEGACY_AUTOLOAD is unset. md_setup_drive() in md-autodetect.c calls blkdev_get_by_dev(), assuming this implicitly creates the block device. Fix this by attempting to md_alloc() the array first. As in the probe path, ignore any error as failure is caught by blkdev_get_by_dev() anyway.

md: rewrite md_setup_drive to avoid ioctls md_setup_drive knows it works with md devices, so it is rather pointless to open a file descriptor and issue ioctls. Just call directly into the relevant low-level md routines after getting a handle to the device using blkdev_get_by_dev instead.
