block: fix bogus compiler warnings in blk-merge.c The compiler can't figure out that bvprv is initialized whenever 'prev' is set to 1 as well. Use a pointer to bvprv instead, setting it to NULL initially, and get rid of the 'prev' tracking. This dumbs it down enough that gcc is happy. Signed-off-by: Jens Axboe <axboe@fb.com>
