[PATCH 4.4 17/64] i40e: Fix of memory leak and integer truncation in i40e_virtchnl.c

[Greg Kroah-Hartman]

From: Martyna Szapar <martyna.szapar@xxxxxxxxx>

commit 24474f2709af6729b9b1da1c5e160ab62e25e3a4 upstream.

Fixed possible memory leak in i40e_vc_add_cloud_filter function:
cfilter is being allocated and in some error conditions
the function returns without freeing the memory.

Fix of integer truncation from u16 (type of queue_id value) to u8
when calling i40e_vc_isvalid_queue_id function.

[bwh: Backported to 4.4: i40e_vc_add_cloud_filter() does not exist
 but the integer truncation is still possible]
