File btrfs-progs-convert-do-not-clear-header-rev.patch of Package btrfsprogs.5036

From: Liu Bo <bo.li.liu@oracle.com>
Subject: Btrfs-progs: convert: do not clear header rev
Git-commit: 1d46d6ba2c888b55c064d5c3c4cb49902e201279
Patch-mainline: v4.11.1
References: bsc#1042369

So btrfs_set_header_flags() vs btrfs_set_header_flag, the difference is
sort of similar to "=" vs "|=", when creating and initialising a new
extent buffer, convert uses the former one which clears header_rev by
accident.
