btrfs: remove unused condition check in btrfs_page_mkwrite()

Browse Source 
The condition '!ret2' is always true. commit 717beb96d9 ("Btrfs: fix
regression in btrfs_page_mkwrite() from vm_fault_t conversion") left
behind the check after moving this code out of the goto, so remove the
unused condition check.
