block/iscsi:use the flags in iscsi_open() prevent Clang warning

Clang static code analyzer show warning:
  block/iscsi.c:1920:9: warning: Value stored to 'flags' is never read
        flags &= ~BDRV_O_RDWR;
        ^        ~~~~~~~~~~~~

In iscsi_allocmap_init() only checks BDRV_O_NOCACHE, which
is the same in both of flags and bs->open_flags.
We can use the flags instead bs->open_flags to prevent Clang warning.
