[PATCH] Documentation: fix docs build error after source file removed

[Randy Dunlap]

From: Randy Dunlap <rdunlap@xxxxxxxxxxxxx>

The pci/htirq.c file was removed so remove it from the documentation
file also.

Error: Cannot open file ../drivers/pci/htirq.c
WARNING: kernel-doc '../scripts/kernel-doc -rst -enable-lineno -export ../drivers/pci/htirq.c' failed with return code 2

Fixes: fd2fa6c18b72 ("x86/PCI: Remove unused HyperTransport interrupt support")
