Clang's version of -Wunused-but-set-variable recently gained support for
unary operations, which reveals two unused variables:
fs/btrfs/block-group.c:2949:6: error: variable 'num_started' set but not used [-Werror,-Wunused-but-set-variable]
int num_started = 0;
^
fs/btrfs/block-group.c:3116:6: error: variable 'num_started' set but not used [-Werror,-Wunused-but-set-variable]
int num_started = 0;
^
2 errors generated.
These variables appear to be unused from their introduction, so just
remove them to silence the warnings.

commit 6d4a6b515c39f1f8763093e0f828959b2fbc2f45 upstream.
Clang's version of -Wunused-but-set-variable recently gained support for
unary operations, which reveals two unused variables:
fs/btrfs/block-group.c:2949:6: error: variable 'num_started' set but not used [-Werror,-Wunused-but-set-variable]
int num_started = 0;
^
fs/btrfs/block-group.c:3116:6: error: variable 'num_started' set but not used [-Werror,-Wunused-but-set-variable]
int num_started = 0;
^
2 errors generated.
These variables appear to be unused from their introduction, so just
remove them to silence the warnings.
