ata: libata-eh: fix sloppy result type of ata_internal_cmd_timeout() 

ata_internal_cmd_timeout() returns *unsigned long* timeout in ms, however
ata_exec_internal_sg() passes that timeout to msecs_to_jiffies() that takes
just *unsigned int*.  Change ata_internal_cmd_timeout()'s result type to
*unsigned int* as well, also updating the *struct* ata_eh_cmd_timeout_ent
and the command timeout tables -- all timeouts fit into *unsigned int* but
we have to change ULONG_MAX to UINT_MAX...
