smb: client: fix file type corruption in posix_reparse_to_fattr()

Setting the file type in cf_mode without clearing the existing S_IFMT
bits first is wrong as it corrupts the file type when cf_mode already
has type bits set (e.g. S_IFREG | S_IFCHR == S_IFLNK).

Use a local ftype variable to collect the new file type and apply it
after validation succeeds, clearing S_IFMT and setting the new type in
a single assignment.  This avoids stripping cf_mode on malformed
reparse points where the function returns false early.
