usb: gadget: s3c: Fix incorrect resources releasing
Since commit 188db4435ac6 ("usb: gadget: s3c: use platform resources"), 'request_mem_region()' and 'ioremap()' are no more used, so they don't need to be undone in the error handling path of the probe and in the remove function. Remove these calls and the unneeded 'rsrc_start' and 'rsrc_len' global variables.
