fs: use scoped_with_init_fs() for kernel_read_file_from_path_initns()

Browse source

Replace the manual init_task root retrieval with scoped_with_init_fs()
to temporarily override current->fs. This allows using the simpler
filp_open() instead of the init_root() + file_open_root() pattern.

kernel_read_file_from_path_initns() ← fw_get_filesystem_firmware() ←
_request_firmware() ← request_firmware_work_func() ← kworker (async
firmware loading)

Also called synchronously from request_firmware() which can be user or
kthread context.
