[PATCH] drivers: md: Mark the function btree_insert_fn() as staticin btree.c

[Rashika Kheria]

This patch marks the function btree_insert_fn() as static in
bcache/btree.c because it is not used outside this file.

Thus, it also eliminates the following warning in bcache/btree.c:
drivers/md/bcache/btree.c:2220:5: warning: no previous prototype for âbtree_insert_fnâ [-Wmissing-prototypes]
