smb/client: fix out-of-bounds read in symlink_data()

In the Linux kernel, the following vulnerability has been resolved:

smb/client: fix out-of-bounds read in symlink_data()

Since smb2_check_message() returns success without length validation for
the symlink error response, in symlink_data() it is possible for
iov->iov_len to be smaller than sizeof(struct smb2_err_rsp). If the buffer
only contains the base SMB2 header (64 bytes), accessing
err->ErrorContextCount (at offset 66) or err->ByteCount later in
symlink_data() will cause an out-of-bounds read.
