lxip: fix timer deletion and modification

Browse Source 
Linux del_timer() and mod_timer() return if the timer was pending before
the modification. Additionally, these functions are potentially called
from handler function of the timer to modify and, therefore, checking
for timeout != INVALID_TIMEOUT is not sufficient as the timeout is
indeed valid when the handler is executed.
