[PATCH 2/3] fs/ext2/inode: Fix a type cast error for fsdax

[Huaisheng Ye <yehs2007-ytc+IHgoah0@public.gmane.org>]

From: Huaisheng Ye <yehs1-6jq1YtArVR3QT0dZR+AlfA@public.gmane.org>

The type of offset within struct iomap is loff_t, which represents
file offset of mapping.

In ext2_iomap_begin, iomap->offset shall be given a type cast as
loff_t instead of u64.
