[PATCH net] bnxt: apply computed clamp value for coalece parameter

[Jonathan Lemon <jonathan.lemon@gmail.com>]

After executing "ethtool -C eth0 rx-usecs-irq 0", the box becomes
unresponsive, likely due to interrupt livelock.  It appears that
a minimum clamp value for the irq timer is computed, but is never
applied.

Fix by applying the corrected clamp value.
