net: zynq: Free allocated buffers in case of error
Driver probe function is called again and again in case of error.
Malloc space is getting full which is is reported by:
Insufficient RAM for page table: 0x15000 > 0x14000.
Please increase the size in get_page_table_size()
### ERROR ### Please RESET the board ###
The patch is freeing allocated buffers on error path to avoid panic.
