isdn: hisax: set error code on failure

In function hfc4s8s_probe(), the value of return variable err should be
negative on failures. However, when the call to request_region() returns
NULL, the value of err is 0. This patch fixes the bug, assigning
"-EBUSY" to err on the path that request_region() fails.
