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.
