Subject: xz: cleanup CRC32 edits from 2018
Date: Sun, 21 Jul 2024 16:36:24 +0300
In 2018, a dependency on <linux/crc32poly.h> was added to avoid
duplicating the same constant in multiple files. Two months later it was
found to be a bad idea and the definition of CRC32_POLY_LE macro was moved
into xz_private.h to avoid including <linux/crc32poly.h>.
xz_private.h is a wrong place for it too. Revert back to the upstream
version which has the poly in xz_crc32_init() in xz_crc32.c.

Fixes: faa16bc404d7 ("lib: Use existing define with polynomial")
Fixes: 242cdad873a7 ("lib/xz: Put CRC32_POLY_LE in xz_private.h")
