[PATCH -next] scsi: message: fusion: Fix returned errno code

[Yang Li]

The callers of initChainBuffers() and PrimeIocFifos() only
cares about gross success/failure, but we still might as well
resolve the following smatch warnings and fix the other error
paths as well:

drivers/message/fusion/mptbase.c:4330 initChainBuffers() warn: returning
-1 instead of -ENOMEM is sloppy
drivers/message/fusion/mptbase.c:4404 initChainBuffers() warn: returning
-1 instead of -ENOMEM is sloppy
