[PATCH] cxl: Plug irq_bitmap getting leaked in cxl_context

[Vaibhav Jain <vaibhav@linux.vnet.ibm.com>]

This patch plugs the leak of irq_bitmap, allocated as part of
initialization of cxl_context struct; during the call to
afu_allocate_irqs. The bitmap is now release during the call to function
afu_release_irqs.
