bootm: fix size arg of flush_cache() in bootm_load_os().
Variable _load_end_ points to end address of uncompressed buffer
(*not* uncomress_buffer_end / sizeof(ulong)), so multipling uncompressed
size with sizeof(ulong) is grossly incorrect in flush_cache().
It might lead to access of address beyond valid memory range and hang the CPU.
Tested on MIPS architecture by using compressed(gzip, lzma)
and uncompressed uImage.
