btrfs: remove set but not used variable 'num_pages'
Fixes gcc '-Wunused-but-set-variable' warning:
fs/btrfs/ioctl.c: In function 'btrfs_extent_same':
fs/btrfs/ioctl.c:3260:6: warning:
variable 'num_pages' set but not used [-Wunused-but-set-variable]
It not used any more since commit 9ee8234e6220 ("Btrfs: use
generic_remap_file_range_prep() for cloning and deduplication")
