This change improves the usability of the `dumptxoutset` RPC in two ways,
in the case that an invalid path is passed:
1. return from the RPC immediately, rather then when the file is first
tried to be written (which is _after_ calculating the UTXO set hash)
2. return a proper return code and error message instead of the cryptic
"CAutoFile::operator<<: file handle is nullptr: unspecified
iostream_category error" (-1)
