ixgbe: Fix unreachable retry logic in combined and byte I2C write functions

The current implementation of `ixgbe_write_i2c_combined_generic_int` and
`ixgbe_write_i2c_byte_generic_int` sets `max_retry` to `1`, which makes
the condition `retry < max_retry` always evaluate to `false`. This renders
the retry mechanism ineffective, as the debug message and retry logic are
never executed.

This patch increases `max_retry` to `3` in both functions, aligning them
with the retry logic in `ixgbe_read_i2c_combined_generic_int`. This
ensures that the retry mechanism functions as intended, improving
robustness in case of I2C write failures.
