subsys: mgmt: Fix handler search

Allow to implement the same SMP group by multiple modules and iterate over all groups, so it is possible to use RESET command, implemented by Zephyr module and prvide custom BOOTLOADER_INFO command implementation.

Allow to implement the same SMP group by multiple modules

Not a supported operation, if you want a custom implementation you must create a full implementation and disable the original, this is by design

Is there any reasonable way to set the bootloader name for other bootloaders than MCUboot?

Have created #78285 this allows you to add custom response, now you might think "that's a problem because it will return two responses" - you just need to add your return value, then return an rc error code of MGMT_ERR_EOK

Thank you, that sounds good!
So - the callback shall return MGMT_CB_ERROR_RC, use zse to build the response and set err_rc to MGMT_ERR_EOK?

Apart from that - the dependency to the MCUboot must be removed to use it 🙂

if BOOTLOADER_MCUBOOT

config MCUMGR_GRP_OS_BOOTLOADER_INFO
	bool "Bootloader information"
	help
	  Allows to query MCUmgr about bootloader used by device and various bootloader
	  parameters.

endif # BOOTLOADER_MCUBOOT

#78312 and yes

Improvement not needed. Customizable bootloader name to be implemented in #78312 and #78285.
