[PATCH 14/26] rv/rvgen: remove redundant initial_state removal

[Wander Lairson Costa <wander@redhat.com>]

Remove an unnecessary and incorrect list removal operation in the
automata state variable processing. The code attempted to remove
initial_state from the states list, but this element was never
added to the list in the first place. States with the __init_
prefix are explicitly excluded from the states list during the
parsing loop, with only the initial_state variable being set
from them.

Calling remove() on an element that does not exist in a list
raises a ValueError. This code would have failed during execution
when processing any DOT file containing an initial state marker.
The subsequent insert operation at index 0 correctly adds the
initial_state to the beginning of the states list, making the
removal operation both incorrect and redundant.
