kernel: prohibit changing cache attributes (SG_CACHED|SG_DEVICE) in segattach(), set SG_RONLY in data2txt()
the user should not be able to change the cache
attributes for a segment in segattach() as this
can cause the same memory to be mapped with
conflicting attributes in the cache.
SG_TEXT should always be mapped with SG_RONLY
attribute. so fix data2txt() to follow the rules.
