x86/fpu: Fix fpu__activate_fpstate_read() and update comments
fpu__activate_fpstate_read() can be called for the current task
when coredumping - or for stopped tasks when ptrace-ing.
Implement this properly in the code and update the comments.
This also fixes an incorrect (but harmless) warning introduced by
one of the earlier patches.
