fix(usbd/dcd_dwc2): Fixed epin counter assert, update buffer name for TU_LOG > 1

[roma-jam]

Requirements

1. When TU_LOG configured with value > 1 we need to provide correct name for TU_LOG_MEM() macros.
2. This PR contain two small fixes, which are crucial for using device configuration with fully load EP amount.
   ESP32S2/S3 and ESP32P4.

Description

1. Flushing _dcd_data.allocated_epin_count to zero while:
   • dcd_edpt_close_all() as we will allocate FIFO for EP0 later in dfifo_device_init(rhport);
   • handle_bus_reset(uint8_t rhport) as we will allocate FIFO for EP0 later in dfifo_device_init(rhport);
2. Fix the usage of counters for TU_ASSERT. When we use _dwc2_controller instead of dwc2_controller we request the ep_in_count member value from the first member, which is FS. This is important, when we run on HS PHY.
3. Changed _usbd_ctrl_buf -> _ctrl_xfer.buffer
