During the rules flush, the rxp_poll_csr_for_value function is called
twice. The rxp_poll_csr_for_value function can fail for two reasons:
1. It could not read the value from register, in which case the
function returns -1.
2. It read a value, but not the value it expected to receive. In this
case it returns -EBUSY.
When the function fails it prints an error message that is relevant only
for a second type of failure. Moreover, for failure of the first type it
prints a value of an uninitialized variable.
In case of success, the function prints a debug message about the number
of cycles it took. This line was probably copied by mistake, since the
variable it reads from, is always equal to 0 and is not an indicator of
the number of cycles.
Remove the incorrect line about the cycles, and reduce the error print
only for the relevant error.
