mm/thp: dead code cleanup in Kconfig

mm/thp: dead code cleanup in Kconfig

There is already an 'if TRANSPARENT_HUGEPAGE' condition wrapping several
config options e.g.  'READ_ONLY_THP_FOR_FS', making the 'depends on'
statement for each of these a duplicate dependency (dead code).

I propose leaving the outer 'if TRANSPARENT_HUGEPAGE...endif' and removing
the individual 'depends on TRANSPARENT_HUGEPAGE' statement from each
option.

This dead code was found by kconfirm, a static analysis tool for Kconfig.
