Revert "ibmvnic: simplify reset_long_term_buff function"
This reverts commit 1c7d45e7b2c29080bf6c8cd0e213cc3cbb62a054.
We tried to optimize the number of hcalls we send and skipped sending
the REQUEST_MAP calls for some maps. However during resets, we need to
resend all the maps to the VIOS since the VIOS does not remember the
old values. In fact we may have failed over to a new VIOS which will
not have any of the mappings.
When we send packets with map ids the VIOS does not know about, it
triggers a FATAL reset. While the client does recover from the FATAL
error reset, we are seeing a large number of such resets. Handling
FATAL resets is lot more unnecessary work than issuing a few more
hcalls so revert the commit and resend the maps to the VIOS.
