[PATCH] XFS: fix the description of 'allocsize=' mount option

[sat]

From: Satoru Takeuchi <takeuchi_satoru at jp.fujitsu.com>

The end-of-file preallocation size is dynamic by default.
So the description about the default size of preallocation
should be removed.

Instead, adding the description about the initial size of
dynamic preallocation is useful for users.
