In commit11fb479ff5("zlib: export S390 symbols for zlib modules"), I added EXPORT_SYMBOL()s to dfltcc_inflate.c but then Mikhail said that these should probably be in dfltcc_syms.c with the other EXPORT_SYMBOL()s. However, that is contrary to the current kernel style, which places EXPORT_SYMBOL() immediately after the function that it applies to, so move all EXPORT_SYMBOL()s to their respective function locations and drop the dfltcc_syms.c file. Also move MODULE_LICENSE() from the deleted file to dfltcc.c.
