fs_mgr_fstab: do an exact match when searching a mount point
Currently when searching a mount point from a fstab, it checks whether the
mount point of an fstab entry is the prefix of a given path, and the
next char after the match is either '\0' or '/'.
However, it will always return the fstab entry with mount point
"/vendor" when searching path is "/vendor", "/vendor/abc" or "/vendor/cde"
in the following fstab. Because "/vendor" is the prefix of "/vendor/abc"
and "/vendor/cde", and the next char after the match is '/'.
/dev/block/platform/.../by-name/vendor /vendor ext4 ro wait
/dev/block/platform/.../by-name/abc /vendor/abc ext4 ro wait
/dev/block/platform/.../by-name/cde /vendor/cde ext4 ro wait
Fix this by performing an exact match when searching the mount point.
