[ Upstream commit 0b397b17a4120cb80f7bf89eb30587b3dd9b0d1d ]

In bnxt_rx_pkt(), if the driver encounters BD errors, it will recycle
the buffers and jump to the end where the uninitailized variable "len"
is referenced.  Fix it by adding a new jump label that will skip
the length update.  This is the most correct fix since the length
may not be valid when we get this type of error.
