treewide: refresh kmalloc_obj() conversionsgrafted
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.

+ help
+ The Freescale hypervisor management driver provides several services
+ to drivers and applications related to the Freescale hypervisor:
+
+ 1) An ioctl interface for querying and managing partitions.
+
+ 2) A file interface to reading incoming doorbells.
+
+ 3) An interrupt handler for shutting down the partition upon
+ receiving the shutdown doorbell from a manager partition.
+
+ 4) A kernel interface for receiving callbacks when a managed
+ partition shuts down.
