nvme: fix command effects log lifetime for multipath heads

KASAN reported a use-after-free when an I/O passthrough command was sent through a multipath namespace head after the controller path that first created the head had been removed:

BUG: KASAN: slab-use-after-free in nvme_command_effects+0x192/0x200 [nvme_core] Read of size 4 at addr ffff888141b14400 by task nvme/19811 nvme_command_effects+0x192/0x200 [nvme_core] nvme_cmd_allowed+0x7e/0x1b0 [nvme_core] nvme_user_cmd.constprop.0+0x1b5/0x450 [nvme_core] nvme_ns_head_chr_ioctl+0xf4/0x2a0 [nvme_core]

Move the log cache to the subsystem, with one entry per command set. Both controllers and namespace heads hold subsystem references, keeping their log pointers valid until subsystem release.
