bnxt_en: Change FW message timeout warning

The firmware advertises a "hwrm_cmd_max_timeout" value to the driver
for NVRAM and coredump related functions that can take tens of seconds
to complete.  The driver polls for the operation to complete under
mutex and may trigger hung task watchdog warning if the wait is too long.
To warn the user about this, the driver currently prints a warning if
this advertised value exceeds 40 seconds:

Device requests max timeout of %d seconds, may trigger hung task watchdog

Initially, we chose 40 seconds, well below the kernel's default
CONFIG_DEFAULT_HUNG_TASK_TIMEOUT (120 seconds) to avoid triggering
the hung task watchdog.  But 60 seconds is the timeout on most
production FW and cannot be reduced further.  Change the driver's warning
threshold to 60 seconds to avoid triggering this warning on all
production devices.  We also print the warning if the value exceeds
CONFIG_DEFAULT_HUNG_TASK_TIMEOUT which may be set to architecture
specific defaults as low as 10 seconds.
