scsi: qla4xxx: Add length check when parsing nlattrs

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

scsi: qla4xxx: Add length check when parsing nlattrs

There are three places that qla4xxx parses nlattrs:

 - qla4xxx_set_chap_entry()

 - qla4xxx_iface_set_param()

 - qla4xxx_sysfs_ddb_set_param()

and each of them directly converts the nlattr to specific pointer of
structure without length checking. This could be dangerous as those
attributes are not validated and a malformed nlattr (e.g., length 0) could
result in an OOB read that leaks heap dirty data.

Add the nla_len check before accessing the nlattr data and return EINVAL if
the length check fails.
