Do not use vp after mount_domount() call as it sets it to NULL on success.
This fixes a panic when starting extended attributes.
Fix mount -o extattr : previous patch fixed a panic but caused operation
to happen on the mount point instead of the mounted filesystem.
Fix the extattr start fix. Looking up the filesystemroot vnode again
does not seems to be reliable. Instead save it before mount_domount()
sets it to NULL.
Move VFS_EXTATTRCTL to mount_domount().  This makes the
fs/puffs/t_fuzz:mountfuzz7, fs/puffs/t_fuzz:mountfuzz8,
and fs/zfs/t_zpool:create tests pass again.  Patch from
manu, discussed on tech-kern and committed at his request.
