net: pasemi: fix error return code in pasemi_mac_open() 

[ Upstream commit aba84871bd ]

Fix to return a negative error code from the error handling
case instead of 0, as done elsewhere in this function.

Fixes: 72b05b9940 ("pasemi_mac: RX/TX ring management cleanup")
Fixes: 8d636d8bc5 ("pasemi_mac: jumbo frame support")
