Subject: [PATCH v2 1/6] smb/server: fix return value of smb2_read()

From: ChenXiaoSong <chenxiaosong@...inos.cn>

STATUS_END_OF_FILE maps to the linux error -ENODATA. Perhaps in the future
we can move client/smb2maperror.c into common/ and then call
map_smb2_to_linux_error() to get the linux error.
