Protect against spurious "bnx0: Double mbuf allocation failure!"
Extract a new function, bnx_add_buf(), from bnx_get_buf().
bnx_add_buf() just tries to add an mbuf to the Rx chain. bnx_get_buf()
tries to allocate an mbuf, first, and then to add the mbuf to the
chain. Use bnx_add_buf() to try to put an mbuf that we took off
of the chain back onto the chain, and use bnx_get_buf() everywhere
This change seems to be in keeping with the author's intent, but
it looks like the code broke at some point.
Thanks to Jarle Greipsland, David Dudley, and others for reporting
this bug and for testing patches.
