* erc32sonic/erc32sonic.c: Minor modifications which enable
	network interface to come up and work for some time before
	getting an error in the SONIC driver.  The error is a bit random,
	sometimes MCLGET (m, M_WAIT) tries to access memory way outside the
	available ram (and traps) while sometimes there is a panic due
	to RBAE/RXEN.
