comp_ctx can be NULL in a very rare case when an admin command is executed
during the execution of ena_remove().
The bug scenario is as follows:
* ena_destroy_device() sets the comp_ctx to be NULL
* An admin command is executed before executing unregister_netdev(),
this can still happen because our device can still receive callbacks
from the netdev infrastructure such as ethtool commands.
* When attempting to access the comp_ctx, the bug occurs since it's set
to NULL
Fix:
Added a check that comp_ctx is not NULL
