Commit Message

misc: make fiber_new non-failing

There are 2 cases when `fiber_new()` may fail:
1. stack allocation failure.
2. guard page protection with `mprotect()` failure.

Let's panic in the 1st case - we panic soon anyway as our policy is to
panic on runtime memory allocation failures.

Let's just drop a line in log in the 2d case, checking stack overflow is
not critical.

Closes #12338

Title: `fiber_new()`\`fiber_new_ex()` are changed to always be
successful
