bnx2x: Remove hidden flow control goto from BNX2X_ALLOC macros

bnx2x: Remove hidden flow control goto from BNX2X_ALLOC macros

BNX2X_ALLOC macros use "goto alloc_mem_err"
so these labels appear unused in some functions.

Expand these macros in-place via coccinelle and
some typing.

Update the macros to use statement expressions
and remove the BNX2X_ALLOC macro.

This adds some > 80 char lines.
