drivers: net: Remove remaining alloc/OOM messages

alloc failures already get standardized OOM
messages and a dump_stack.

For the affected mallocs around these OOM messages:

Converted kmallocs with multiplies to kmalloc_array.
Converted a kmalloc/memcpy to kmemdup.
Removed now unused stack variables.
Removed unnecessary parentheses.
Neatened alignment.
