yi chen 03822bb5a6 fix(vfs): use MAX_FDS instead of VFS_MAX_COUNT when clearing fd table on unregister

esp_vfs_unregister_with_id() scanned only the first VFS_MAX_COUNT
(default 8, max 20) slots of s_fd_table[MAX_FDS] (MAX_FDS = FD_SETSIZE,
64 on non-Cygwin targets) when clearing stale references to the
unregistered VFS. Every other loop over s_fd_table in this file
(and in vfs_calls.c) correctly bounds on MAX_FDS.

Any global fd >= VFS_MAX_COUNT that was still open against the VFS
being unregistered was left with a stale vfs_index pointing at a slot
that esp_get_free_index() can immediately hand out to the next
esp_vfs_register*() call, causing later operations on that fd to be
routed into an unrelated filesystem's context.
