The STFLE bit 147 indicates whether the ESSA no-DAT operation code is
valid, the bit is not normally provided to the host; the host is
instead provided with an SCLP bit that indicates whether guests can
support the feature.
This patch:
* enables the STFLE bit in the guest if the corresponding SCLP bit is
present in the host.
* adds support for migrating the no-DAT bit in the PGSTEs
* fixes the software interpretation of the ESSA instruction that is
used when migrating, both for the new operation code and for the old
"set stable", as per specifications.
