Subject: [PATCH] brd: remove max_hw_sectors queue limit
Git-commit: 36582a5a456100ebe4983e3d63b8cbc7e62a0ddc
Patch-mainline: v5.5-rc1
References: bsc#1175995,jsc#SLE-15608
Now we depend on blk_queue_split() to respect most of queue limit
(the only one exception could be dma alignment), however
blk_queue_split() isn't used for brd, so this limit isn't respected
since v4.3.
Also max_hw_sectors limit doesn't play a big role for brd, which is
added since brd is added to tree for unknown reason.
So remove it.
