hash: fix doc about thread/process safety
rte_hash_hash is multi-thread safe but not multi-process safe because of the use of function pointers. Previous document and comment says the other way around. This commit fixes the issue.

* The use of function pointers between multiple processes running based of different compiled binaries is not supported,
since the location of a given function in one process may be different to its location in a second.

since it uses a pointer to the hash function internally.
To work around this issue, it is recommended that multi-process applications perform the hash calculations by directly calling
