Don't use ino_t in dumprestore protocol definition.
Since ino_t size is about to change to 64-bits, replace ino_t used in
dump protocol definition with 32-bit dump_ino_t to preserve backward
compatibility. At some point, it may be necessary to use spare fields
in struct in order to fully support 64-bit inode numbers.
