[PATCH] btrfs: Remove dead code

[Muhammad Usama Anjum <usama.anjum@collabora.com>]

Local variable stop_loop is assigned only once, to a constant value 0,
making it effectively constant through out its scope. This constant
variable is guarding deadcode. The two if conditions can never be true.
Remove the variable and make the logic simple.
