btrfs: zoned: introduce block group context to btrfs_eb_write_context
For metadata write out on the zoned mode, we call
btrfs_check_meta_write_pointer() to check if an extent buffer to be written
is aligned to the write pointer.
We look up a block group containing the extent buffer for every extent
buffer, which takes unnecessary effort as the writing extent buffers are
mostly contiguous.
Introduce "zoned_bg" to cache the block group working on. Also, while
at it, rename "cache" to "block_group".
