[ Upstream commit 37733bffda3285d18bd1d72c14b3a1cf39c56a5e ]
fw_running assumes that memory can be retrieved only after alive.
This assumption is no longer true as we support dump before alive.
To avoid invalid access to the NIC, check that STATUS_DEVICE_ENABLED
bit in trans status is set before dumping instead of the prior check.

[ Upstream commit c8d8f3911135921ace8e939ea0956b55f74bf8a0 ]
EWRD ACPI table contains up to 3 additional sar profiles.
According to the BIOS spec, the table contains a n_profile
variable indicating how many additional profiles exist in the
table.
Currently we check that n_profiles is not <= 0.
But according to the BIOS spec, 0 is a valid value,
and it can't be < 0 anyway because we receive that from ACPI as
an unsigned integer.
