[ide] fix IRQ masking in ide_do_request()
Revert to previous way of handling masked_irq argument.
Reported to fix problems with shared PCI IRQs.

<[EMAIL PROTECTED](none)> (05/02/24 1.2051)
[ide] fix build for built-in hpt366 and modular ide-disk
* always call __ide_do_rw_disk() in ide_do_rw_disk()
* modify ide_hwif_t->rw_disk hook accordingly
* update and cleanup hpt372n_rw_disk()
(the only user of ide_hwif_t->rw_disk hook)
* make __ide_do_rw_disk() static + fix comment

[ide] make 1-bit fields unsigned
It's a bit difficult to have a value and a sign bit in a
1-bit field.
Fix (90) boolean/bitfield sparse warnings:
include/linux/ide.h:937:18: warning: dubious one-bit signed bitfield
include/linux/ide.h:939:17: warning: dubious one-bit signed bitfield
