btrfs: trace: Remove unnecessary fs_info parameter for btrfs__reserve_extent event class

Browse Source 
fs_info can be extracted from btrfs_block_group_cache, and all
btrfs_block_group_cache is created by btrfs_create_block_group_cache()
with fs_info initialized, no need to worry about NULL pointer
dereference.
