Bluetooth: Annotate struct hci_drv_rp_read_info with __counted_by_le()

Linux kernel mirror (for testing) git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git

kernel os linux

Add the __counted_by_le() compiler attribute to the flexible array
member 'supported_commands' to improve access bounds-checking via
CONFIG_UBSAN_BOUNDS and CONFIG_FORTIFY_SOURCE.
