Takashi Yano ae181b0ff1 Cygwin: lockf: Make lockf() return ENOLCK when too many locks
Previously, lockf() printed a warning message when the number of locks
per file exceeds the limit (MAX_LOCKF_CNT). This patch makes lockf()
return ENOLCK in that case rather than printing the warning message.

Fixes: 31390e4ca643 ("(inode_t::get_all_locks_list): Use pre-allocated buffer in i_all_lf instead of allocating every lock.  Return pointer to start of linked list of locks.")
