[PATCH] kernel: Introduce enable_and_queue_work() convenience function

[Allen Pais <apais@linux.microsoft.com>]

The enable_and_queue_work() function is introduced to streamline
the process of enabling and queuing a work item on a specific
workqueue. This function combines the functionalities of
enable_work() and queue_work() in a single call, providing a
concise and convenient API for enabling and queuing work items.

The function accepts a target workqueue and a work item as parameters.
It first attempts to enable the work item using enable_work(). If the
enable operation is successful, the work item is then queued on the
specified workqueue using queue_work(). The function returns true if
the work item was successfully enabled and queued, and false otherwise.

This addition aims to enhance code readability and maintainability by
providing a unified interface for the common use case of enabling and
queuing work items on a workqueue.
