habanalabs/gaudi2: return to reset upon SM SEI BRESP error

Due to a H/W issue in the LBW path to the PCIE_DBI MSI-X doorbell, there
were false sporadic error responses in SM when it was configured to
write to there, and hence no reset was done as part of handling the
relevant event.
Now that the virtual MSI-X doorbell is used, such errors in SM are not
expected and reset shouldn't be skipped.
