Alexey Dobriyan 74f3b63c7b block: fix integer overflow in BLKSECDISCARD 
[ Upstream commit 697ba0b6ec4ae04afb67d3911799b5e2043b4455 ]

Fix CVE: CVE-2024-36917

Partly ported to tk4, since blk_ioctl_secure_erase()
introduced in v5.19

I independently rediscovered

	commit 22d24a544b0d49bbcbd61c8c0eaf77d3c9297155
	block: fix overflow in blk_ioctl_discard()

but for secure erase.

Same problem:

	uint64_t r[2] = {512, 18446744073709551104ULL};
	ioctl(fd, BLKSECDISCARD, r);

will enter near infinite loop inside blkdev_issue_secure_erase():

	a.out: attempt to access beyond end of device
	loop0: rw=5, sector=3399043073, nr_sectors = 1024 limit=2048
	bio_check_eod: 3286214 callbacks suppressed
