[PATCH 03/13] can: mcp25xxfd: mcp25xxfd_ring_free(): fix memory leak during cleanup

[Marc Kleine-Budde]

From: Dan Carpenter <dan.carpen...@oracle.com>

This loop doesn't free the first element of the array.  The "i > 0" has
to be changed to "i >= 0".

Fixes: 55e5b97f003e ("can: mcp25xxfd: add driver for Microchip MCP25xxFD SPI 
CAN")
