Subject: [PATCH] 9pfs: use g_malloc0 to allocate space for xattr
9p back-end first queries the size of an extended attribute,
allocates space for it via g_malloc() and then retrieves its
value into allocated buffer. Race between querying attribute
size and retrieving its could lead to memory bytes disclosure.
Use g_malloc0() to avoid it.

Move dst calculation into the loop, so we apply the mask on each
interation and will not overflow vga memory.
