Gil Portnoy 20c8442dc1 ksmbd: enforce FILE_READ_ATTRIBUTES on SMB_FIND_FILE_POSIX_INFORMATION 
find_file_posix_info() in smb2_query_info() returns file metadata (owner
uid, group gid, mode, inode, size, allocation size, hard-link count and all
four timestamps) but performs no per-handle access check. Every sibling
query handler gates on the handle's granted access first --
get_file_basic_info(), get_file_all_info(), get_file_network_open_info()
and get_file_attribute_tag_info() all reject a handle lacking
FILE_READ_ATTRIBUTES_LE with -EACCES. The POSIX handler is gated only by
the connection-scoped tcon->posix_extensions flag, which is not a
per-handle authorization, so a handle opened with only FILE_WRITE_DATA is
correctly denied FileBasicInformation yet is allowed the strict-superset
POSIX info. Mirror the FILE_READ_ATTRIBUTES_LE gate the sibling info
handlers already use.

Fixes: e2f34481b2 ("cifsd: add server-side procedures for SMB3")
