btrfs: remove redundant auto reclaim log message

Browse Source 
Remove the log message before reclaiming a chunk in
btrfs_reclaim_bgs_work(). Especially with automatic block-group
reclaiming these messages spam the kernel log.

Note there is also a tracepoint for the same condition to ease debugging.
