xz: cleanup CRC32 edits from 2018

Browse source

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.
