Kernel: Don't lock the scheduler in ProcFSOverallProcesses::try_generate

This used to be needed to protect accesses to Process::all_instances.
That list now has a more granular lock, so we don't need to take the
scheduler lock.

This fixes a crash when we try to access a locked Thread::m_fds in the
loop, which calls Thread::block, which then asserts that the scheduler
lock must not be locked by the current process.

Fixes #13617
