pk does not release file handles on an fclose

[MarkHillHuawei]

This short program illustrates the problem: test00.c:

include

include

include

int main() { FILE *fd; int open_files=0; while (1){ fd = fopen("test00.c","r"); fclose(fd); if (fd) open_files++; else break; } printf("errno:%d\nopen:%d\n",errno,open_files); }

It should never terminate but fails after about 125 iterations (close to MAX_FILES value set in pk/file.c), the behaviour is the same as when "fclose" is commented out.

Thanks for providing a test case, @MarkHillHuawei. Fixed.
