btrfs: use num_extent_folios() in for loop bounds
As the helper num_extent_folios() is now __pure, we can use it in for
loop without storing its value in a variable explicitly, the compiler
will do this for us.
The effects on btrfs.ko is -200 bytes and there are stack space savings
too:
btrfs_clone_extent_buffer -8 (32 -> 24)
btrfs_clear_buffer_dirty -8 (48 -> 40)
clear_extent_buffer_uptodate -8 (40 -> 32)
set_extent_buffer_dirty -8 (32 -> 24)
write_one_eb -8 (88 -> 80)
set_extent_buffer_uptodate -8 (40 -> 32)
read_extent_buffer_pages_nowait -16 (64 -> 48)
find_extent_buffer -8 (32 -> 24)
