It appears the biosize mount option hasn't been documented as a valid
option since 2005, remove it.

There is no real need for the local variables here - either they
are applied to the mount structure, or if the noalign mount option
is set the mount will fail entirely if either is set. Removing
them helps cleaning up the mount API conversion.

remove it.

Rework xfs_parseargs to fill out the default value and then parse the
option directly into the mount structure, similar to what we do for
other updates, and open code the now trivial updates based on on the
on-disk superblock directly into xfs_mountfs.
Note that this change rejects the allocsize=0 mount option that has been
documented as invalid for a long time instead of just ignoring it.

Replace XFS_MOUNT_COMPAT_IOSIZE with an inverted XFS_MOUNT_LARGEIO flag
that makes the usage more clear.
