shared/uhid.c: Fix 32-bit integer truncation
Id paramter given to bt_uhid_set_report_reply() and
bt_uhid_get_report_reply() corresponds to a 32-bit tag value passed to
us from the kernel side of UHID. Specifying this parameter as uint8_t
breaks the synchronization after 255 request and renders the attached
BLE device inoperable.
Fixes: 92ed637ab2bc ("shared/uhid: Add dedicated functions for each UHID opcode")

hog-lib: Fix 32-bit integer truncation
Id paramter stored in getrep_id and setrep_id corresponds to a 32-bit
tag value passed to us from the kernel side of UHID. Specifying this
parameter as uint16_t breaks the synchronization after 65536 request
and renders the attached BLE device inoperable.
