mount_9p: fix writing to a file opened with write-only mode
With the page cache, writing data to a file may demand to read contents
from a storage to fill a page in the page cache first.
Opening a file with write-only mode by a user lets a mount_9p process
open a file with write-only mode too at a 9p server. Thus, a read
request to the file from the page cache fails.
So we need to open a file always with read mode (internally) even if it
is opened with write-only mode by a user.
Note that the change doesn't mean that mount_9p allows users to read
contents from a file that is opened with write-only mode.
