From: Colin Ian King <colin.king@xxxxxxxxxxxxx>
Currently the u16 req->error_loc is being compared to -1 which
will always be false. Fix this by casting -1 to u16 to fix this.
Detected by clang:
warning: result of comparison of constant -1 with expression of
type 'u16' (aka 'unsigned short') is always false
[-Wtautological-constant-out-of-range-compare]
Fixes: 76574f37bf4c ("nvmet: add interface to update error-log page")
