[PATCH 2/3] module: Change module_enable_{nx/x/ro}() to more explicit names

[Christophe Leroy <christophe.leroy@xxxxxxxxxx>]

It's a bit puzzling to see a call to module_enable_nx() followed by a
call to module_enable_x(). This is because one applies on text while
the other applies on data.

Change name to make that more clear.
