Removed unused return variable and replaced it with returning
the value directly. Also removed the unnecessary forward declaration.

Signed-off-by: Aliasgar Surti <aliasgar.surti500@gmail.com>
---
v2: Made btrfs_destroy_delayed_refs() as void and removed its declaration
v3: Reverted back the change where the function was made void from int
