[Skiboot] [PATCH 11/13] libflash: fix memory leak on flash_exit()

[Stewart Smith]

LeakSanitizer caught this with libflash/test/test-flash.c:

Direct leak of 4096 byte(s) in 1 object(s) allocated from:
    #0 0x7f72546ee850 in malloc (/lib64/libasan.so.4+0xde850)
    #1 0x405ff0 in flash_init libflash/test/../libflash.c:830
    #2 0x408632 in main libflash/test/test-flash.c:382
    #3 0x7f7253540509 in __libc_start_main (/lib64/libc.so.6+0x20509)
