Hi Dan,
xfs_errortag_add() is called by xfs_file_ioctl(), which accept the 1st
argument as signed, i.e,
typedef struct xfs_error_injection {
__s32 fd;
__s32 errtag;
} xfs_error_injection_t;
Should we make it happy as well? Also, the typedef can be converted to
to struct xfs_error_injection by removing the depreciated
xfs_error_injection_t
syntax if so.

Errors go from zero which means no error to XFS_ERRTAG_MAX (22). My
static checker complains that xfs_errortag_add() puts an upper bound on
this but not a lower bound. Let's fix it by making it unsigned.
