====================
bpf: Consolidate sleepable context checks in verifier

The BPF verifier has multiple call-checking functions that independently
validate whether sleepable operations are permitted in the current
context. Each function open-codes its own checks against active_rcu_locks,
active_preempt_locks, active_irq_id, and in_sleepable, duplicating the
logic already provided by in_sleepable_context().

This series consolidates these scattered checks into calls to
in_sleepable_context() across check_helper_call(), check_kfunc_call(),
and check_func_call(), reducing code duplication and making the error
reporting consistent. No functional change.
