hurd: Use __hurd_fail () instead of assigning errno
The __hurd_fail () inline function is the dedicated, idiomatic way of reporting errors in the Hurd part of glibc. Not only is it more concise than '{ errno = err; return -1; }', it is since commit 6639cc10029e24e06b34e169712b21c31b8cf213 "hurd: Mark error functions as __COLD" marked with the cold attribute, telling the compiler that this codepath is unlikely to be executed. In one case, use __hurd_dfail () over the plain __hurd_fail (). Signed-off-by: Sergey Bugaev <bugaevc@gmail.com> Message-Id: <20230520115531.3911877-1-bugaevc@gmail.com>
