[ Upstream commit cb47d16ea21045c66eebbf5ed792e74a8537e27a ]

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

Fixes: 469981b17a4f ("qed: Add unaligned and packed packet processing")
Fixes: fcb39f6c10b2 ("qed: Add mpa buffer descriptors for storing and processing mpa fpdus")
Fixes: 1e28eaad07ea ("qed: Add iWARP support for fpdu spanned over more than two tcp packets")
