xen-netback: remove pointless clause from if statement

[ Upstream commit 0576eddf24df716d8570ef8ca11452a9f98eaab2 ]

This patch removes a test in start_new_rx_buffer() that checks whether
a copy operation is less than MAX_BUFFER_OFFSET in length, since
MAX_BUFFER_OFFSET is defined to be PAGE_SIZE and the only caller of
start_new_rx_buffer() already limits copy operations to PAGE_SIZE or less.
