Clean up error message reported after \password encryption failure.

Experimenting with FIPS mode enabled, I saw

regression=# \password joe
Enter new password for user "joe":
Enter it again:
could not encrypt password: disabled for FIPS
out of memory

because PQencryptPasswordConn was still of the opinion that "out of
memory" is always appropriate to print.

Minor oversight in b69aba745.  Like that one, back-patch to v14.
