Subject: xen/netback: Properly initialize credit_bytes

From: Ross Lagerwall <ross.lagerwall@citrix.com>

[ Upstream commit ce0e5c522d3924090c20e774359809a7aa08c44c ]

Commit e9ce7cb6b107 ("xen-netback: Factor queue-specific data into queue
struct") introduced a regression when moving queue-specific data into
the queue struct by failing to set the credit_bytes field. This
prevented bandwidth limiting from working. Initialize the field as it
was done before multiqueue support was added.
