lizhe 3a83e289e4 jffs2: Allow setting rp_size to zero during remounting
[ Upstream commit cd3ed3c73ac671ff6b0230ccb72b8300292d3643 ]

Set rp_size to zero will be ignore during remounting.

The method to identify whether we input a remounting option of
rp_size is to check if the rp_size input is zero. It can not work
well if we pass "rp_size=0".

This patch add a bool variable "set_rp_size" to fix this problem.
