[PATCH] netvsc: fix unititialized return value in variable ret

[Colin King]

From: Colin Ian King <colin.king@xxxxxxxxxxxxx>

It is possible for an uninitialized value of ret to be returned
so fix this by initializing ret to zero.

Detected by CoverityScan, CID#1420762 ("Uninitialized scalar variable")

Fixes: 163891d7d429 ("netvsc: handle offline mtu and channel change")
