[PATCH v4 01/10] ntfs: keep the EA presence flag after creating the first entry

[Baolin Liu <liubaolin12138@163.com>]

From: Baolin Liu <liubaolin@kylinos.cn>

The successful EA update path tests ea_info_qsize when updating
NInoHasEA, but this size excludes the appended entry. Creating the first
EA, or replacing the only entry, can therefore clear the cached presence
flag despite a successful update. Reads then return ENODATA until
reload.

Include the appended entry in the size used for the presence test.
