EALREADY:
Both Linux(asm-generic/errno.h) and FreeBSD(sys/sys/errno.h) regard it as "Operation already in progress"
ESTALE:
Linux specifically removed the "NFS" description, and we may not only use it for NFS
0ca4343518
The ECANCELED and EOWNERDEAD also use different strings from Linux's header, but their meanings are same, and NuttX's description are more likely to obey POSIX 1003.1-2008, so not changing them.
