This is another run of the Coccinelle script for converting kmalloc()
family of allocations to kmalloc_obj() via the existing rules in
scripts/coccinelle/api/kmalloc_objs.cocci
This catches both the set of kmalloc() uses added since the first
kmalloc_obj() conversions in v7.0 and adds a large group missed in the
first pass due to Coccinelle not interacting well with the cleanup.h
scoped_...() family of macros[1]. I worked around this with spatch's
"--macro-file" argument to a file with all the scoped_...() macros mapped
to Coccinelle's YACFE_ITERATOR[2] as that was the closest viable control
flow indicator I could find.
Build tested allmodconfig on x86, arm64, arm, loongarch, mips, powerpc,
riscv, and s390 with no new warnings.

Small send control queue message buffers are managed and reused by
libie itself, bigger send buffers are consumed. All are tracked with
the unique transaction (Xn) ids until they receive response or time out.
Responses can be received out of order, therefore transactions are stored
in an array and tracked though a bitmap. Rx buffers utilize page_pool.
Pre-allocated DMA memory is used where possible. It reduces the driver
overhead in handling memory allocation/free and message timeouts.

Libie will now support control queue setup and configuration APIs. These
are mainly used for mailbox communication between drivers and control
plane.
Make use of the libeth_rx page pool support for managing controlq buffers.
